WO2000055782A2 - Demand aggregation through online buying groups - Google Patents

Abstract

An online buying group (referred to herein as a "co-op") is formed for the specific purpose of purchasing a particular product at (102) by defining a start time, end time, critical mass, any minimum number of units offered, any maximum number of units offered, starting price and product cost curve. As data is gathered from buyers, by means of their making binding purchase offers, the co-op is modified at (108) using a pricing tool, so as to take into account for this market data in the definition of the price curve. A buyer chooses a product co-op of interest at (114). The buyer is presented with the following essential co-op information: current price, closing time, next price level (as defined by a price curve visibility window and the price curve) sufficient to entice the buyer to make an offer. Once a buyer has made up his mind, the decision must be made at (116) to offer a purchase price which includes the current price, guaranteeing availability if critical mass has been achieved, or to make an offer at a lower price range that can be accepted only if the co-op price drops to that level, which may not occur. Given a decision to make an offer at such lower price, the buyer enters such maximum price at which he is willing to purchase to product at (118). Should the current price drop to the level at which the offer was made, the price contingency is removed from such offer and assuming critical mass is achieved, the offer is accepted at at the close of the co-op at (122), and processed accordingly. Inventory is allocated to fulfill the accepted offer at (126) following the closing of the co-op at (124).

Description

DEMAND AGGREGATION THROUGH ONLINE BUYING GROUPS

BACKGROUND OF THE INVENTION

1. Field of the Invention.

The present invention relates to demand aggregation for goods and services and the computerized operation of global buying groups conducted over electronic networks such as the Internet.

2. Introduction to the Invention.

This invention provides a method and apparatus to globally locate, encourage and enable all buyers wishing to purchase a particular product or service within a given time frame to join forces in a buying group ("co-op") formed specifically to accomplish the desired purchase. The co-op will enable individual buyers to leverage their combined purchasing power to achieve an economic bargain far superior to that attainable by any one buyer acting alone. This superior bargain most often will be reflected in terms of a lower price.

The invention also provides a method and apparatus that allows each buyer an opportunity to increase the volume of any given co-op in order to further increase group buying power within a co-op. It also includes a mechanism through which buyers can form any number of special interest groups, provide their collective wisdom to dictate which products are featured in future co-ops, or even make a market for a given product or service. Other key aspects of the invention include a means to allow unprecedented access to certain market and pricing information derived from co-op member input during the life of each co-op. For example, all buyers wishing to join a co-op must submit a binding offer guaranteeing their willingness to purchase the featured item at or below some maximum price determined by each individual member. This collection of purchase offers provides valuable quantitative data regarding price sensitivity for the featured item. In addition, it permits real time yield management decisions that often will benefit both buyers and suppliers. Specifically, the invention provides data from which a supplier can be informed that if the product price is reduced by a specified amount, the co-op's pool of accepted offers - i.e., final sales - will increase by a specific quantity. The guaranteed increase in volume due to a reduced price would improve its overall yield. Under this scenario, both the co-op buyers and the product supplier benefit from the indicated price reduction.

Other ways in which this invention provides unique benefits to buyers and suppliers of goods and services in electronic commerce are set forth in various parts of this document below.

3. Background. (Prior art)

(Buyer problems to be solved by the invention) The vast majority of retail methods of commerce do not permit any give and take between buyer and seller regarding terms of purchase. Instead they employ a seller-controlled format whereby the seller determines which items are to be offered for sale, when each item will be offered for sale, and the non-negotiable fixed price at which each item will be sold. Traditional stores (including most on-line stores), catalog sales, telemarketing sales, and classified ads all represent examples of this prevalent seller-controlled sales environment.

While the auction sales format permits buyer interaction, it too vests most of the bargaining power in the seller by permitting him or her to select the item to be sold and the time at which it will be offered for sale. Auctions also typically permit the seller to specify a minimum price at which the item may be sold. Moreover, the auction model further deteriorates the power of each individual buyer by pitting him or her against similarly situated buyers, all competing to pay the highest price for the item.

Historically, individual buyers have sought to achieve collective buying power, among other things, by joining a traditional, true "co-op" - i.e., an organization that is actually owned by and operated for the benefit of those using its services. Such organizations usually are comprised of individual members with common business, occupational, or recreational interests. Members of these true coops pay annual membership fees (typically sufficient to cover the operating costs of the co-op entity) for the privileges of membership, which often include access to information, products and services related to the co-op's defined purpose.

Traditional buying co-ops (including those emerging on the Internet up to the date of this invention) have been organized around a common set of interests much broader than a particular product (e.g., a digital camera), or even a narrowly defined product category (e.g., cameras). As a result, the extent to which they can aggregate demand for any given product or service is limited by the organization's defined membership base and topical focus. Historically, this breadth of member commonality was required. Otherwise, the benefits achieved through the co-op would be vastly outweighed by the amount of time, money and energy expended to join and maintain the membership.

At the time of this invention, buying groups organized globally on a purchase by purchase basis do not exist. In addition, there is no single mechanism through which people can quickly and conveniently create or join any special interest group of their choosing for purchasing products through a global electronic network such as the Internet.

(Supplier problems to be solved by the invention)

Traditionally, market data regarding the price buyers are willing to pay for a given product or service has been derived primarily from actual sales data. These estimates fail to capture data regarding instances in which sales were rejected by those deciding not to buy the given product. Obviously, the universe of buyers seriously considering purchasing a new flat screen TV includes not only those who will decide to purchase the item, but any number of people who will conclude the current unilaterally fixed price for the item is too high. Under traditional sales models, there is no practical way to capture the number of potential buyers who rejected the sale based on price. Moreover, there is no way to capture the actual price point at which the potential buyer would have purchased the item. If an invention were to permit access to this data globally for a large pool of potential buyers, the invention would be extremely valuable to suppliers of goods and services in that it would permit better pricing, yield management and marketing decisions.

Further, historically there has been no way for a supplier to predict with certainty the price at which a product must be sold in order to increase sales volume by a specified amount. Under traditional sales models, pricing decisions are made based on estimates, such as anticipated product demand and presumed price sensitivity, in the hope that supply will approximate demand at the selected price. If a supplier of a particular item could rely on guaranteed purchase offers to increase volume at varying levels of acceptable sales prices, such information would be extremely valuable to the supplier. Among other things, it would permit instantaneous, accurate yield management decisions that often would encourage win- win price reductions. The supplier wins by improving his overall yield based on volume, and the buyer wins by getting a lower per unit price.

Further, existing sales models do not offer suppliers a clearly superior means of quickly reducing large quantities of specific product inventory (such as a close out item) in a way that will permit both maximization of yield and fast movement of an extremely large quantity of product. Similarly, there exists no clearly superior sales channel through which a supplier can readily turn to swiftly create an extremely large, global market for a specific product such that the supplier's market share for that product literally could substantially increase overnight. Finally, access to the larger interest groups enabled by this invention present a superior forum for marketing and testing products and services of interest to the membership of a given group. Such activities may be limited to those which are deemed by any given group to be of mutual beneficial to both individual group members and the suppliers of goods and services of interest to such group. Specific examples of e-commerce systems implemented on the Internet or other networks are disclosed in the following issued patents: U.S. Patent 4,789,928, issued December 6, 1988 to Fujisaki; U.S. Patent 5,794,207, issued August 11, 1998 to Walker et al.; U.S. Patent 5,797,127, issued August 18, 1998 to Walker et al.; U.S. Patent 5,835,896, issued November 10, 1998 to Fisher et al. and U.S. Patent 5,845,265, issued December 1, 1998 to Woolston.

4. Benefits of the invention. (Buyers)

The traditional shopping experience - buying goods at stores and malls (whether on line or brick and mortar) - was designed by sellers with the primary purpose of promoting commerce for themselves. Not surprisingly, this prevalent sales model gives the seller virtually all of the power and control associated with a given sales transaction. This invention creates a new shopping experience by essentially reversing certain aspects of the traditional seller-oriented sales model. The result is a far more empowering shopping experience for the buyer.

As shown in Figure 1, a store 10 is simply a collection of products 12. As shown in Figure 2, a mall 14, of course, is a collection of stores 10. Historically, buyers 16 have had to come to the seller's pre-selected and pre-priced collection of products 12 in order to make a purchase. This invention, represented in Figure 3, turns the point of sale into a collection of buyers 16 (the "co-op"), rather than products 12. It further permits these co-ops to be located among any number of other co-ops at an Internet or other network site provided by a business entity implementing the invention. This fundamental shift in structure provides many advantages each discussed in detail below.

By creating a means to globally aggregate a large number of buyers in one place at one time (a co-op), this invention enables a tremendous shift in power from the seller of goods and services to the buyer of goods and services. Rather than permitting the product seller to establish the product's sales price, it permits each buyer to establish a maximum price at which he or she will purchase the product. (Notwithstanding this specification of a maximum acceptable price, all co-op members enjoy the full measure of price reductions achieved through the co-op. Hence, each member^'s offer will be accepted at the co-op's lowest —i.e., the ending ~ price.) Co-op members are further empowered by certain other features of the invention. Specifically, after joining a given co-op each member will be given an opportunity to drive volume to further reduce prices by e-mailing people he or she knows who might be interested in joining the co-op. In this way, every member can help the co-op attain its critical mass (which guarantees the success of the co-op) and surplus volume (which serves to drive prices below previously anticipated levels). In addition, the invention permits buyers to help choose which products and brands will be featured in future co-ops. Through this feature, buyers also can actually create a market for a particular product. For example, this input feature would permit a general query regarding whether there is sufficient buyer interest for a particular style of wristwatch (in which one or more buyers had previously inquired). If sufficient demand for the item exists, a business entity implementing the invention could then seek out a jewelry manufacturer willing to make a large volume of the watches and then offer such items to those who expressed interest and potentially others in a future co-op. The invention's method presents a buying model far superior (from the standpoint of the buyer) to that of the auction sales model. Rather than providing a method by which numerous buyers compete against one another to be the "winner" at the highest price, this method enables buyers to join forces to achieve a lower price at which they all "win." Further, the invention provides an effective method for focused aggregation of purchasing power (1 e., all people currently w ll ng and able to purchase a featured product without regard to their geographic location, profession, or any conflicting or specific personal interests of the individual buyers withm the group) This method of aggregation will generate far greater participation and purchasing power than any traditional co-op To illustrate this point, consider a typical "small business" co-op It likely would generate some demand for a particular premium brand computer pπnter However, it normally would be limited in its geographic reach And even if the co-op were operated globally via the internet, its demand would not encompass all people using the internet who might be interested m buying that particular pπnter. It would include only small business owners (or more likely owners of a particular type of small business) The ability to quickly, conveniently and economically form narrowly defined co-ops is a cπtical aspect of this invention which is made possible by the technology composing this invention when coupled with a global electronic network such as the Internet.

The method and apparatus of this invention further provides a means through which individual buyers can aggregate on the basis of broader interest groups for any purpose including access to the latest product and other information of interest to the group. (Benefits to suppliers)

In order to join a co-op, each buyer must determine the maximum pπce at which (or below) he or she is willing to purchase the featured item Such amount is specified in his or her binding purchase offer That offer is guaranteed by the buyer's credit card. All offers including the vaπous amounts at which they are submitted are collected and summaπzed in a database This process enables accurate, real-time yield management decisions which can be used to advocate a lower per unit pπce For example, the business entity implementing the invention would be able to represent to a supplier that if the pπce were lowered by $X, the sales volume will increase by an additional 1,000 units. Although the per unit pπce would drop, the supplier^'s overall profit yield may increase due to the substantial increase m volume Hence, this invention eliminates the uncertainty that often makes suppliers reluctant to lower pπces

In addition, the pπcmg data descπbed above represents an extraordmaπly complete picture of the pπce sensitivity with respect to a given product because it captures not only actual sales data, but also price specific data on potential sales that were not completed because of price. Further, this invention enables the feasible collection of various other types of market data such as geographic distribution and other characteristics of the buyers interested in a given product. In addition, it enables a superior way to gauge interest in future products and services.

Further, this invention's method of globally creating buying groups on a purchase by purchase basis brings a vast number of potential buyers to the bargaining table. Consequently, it provides a superior method of quickly moving large quantities of specific products. This will be useful to product suppliers in many ways. For example, a supplier might utilize the invention's sales platform to sell a substantial volume of one product for the specific purpose of increasing its market share. It even would be possible under this example for the supplier to specify a minimum sales volume so that no sales are made unless its market share objectives are met. In addition, a supplier could utilize this invention as a platform for unloading a large volume of specific products nearing the end of their product life cycle. Suppliers might also utilize this invention as a means to accomplish swift inventory leveling for cash flow or financial reporting purposes. While there are existing channels through which suppliers can sell closeout products or accomplish inventory leveling, none provide the ability to quickly move a substantial volume of inventory while still maximizing profit yield in the manner described above.

Finally, membership of any given broader special interest groups that can be created through this invention (e.g., camera enthusiasts) might epitomize the target customer for a particular product or service of a supplier. Possible ready access to such group, as possibly limited by each group membership, could be extremely valuable to suppliers for general marketing, product testing, and other purposes.

Definitions

Certain terms as used herein are defined as follows: Browser: A specific type of client system, referring to an HTTP client enabling the display of various forms of information originating at the server; also capable of sending information, such as requests and personal data, to the server at the request of the end user. A browser is not the only possible or intended client system. Our method and apparatus apply only to the server, and are not dependent on what form of client is used, only that some client exists as the means of input.

Co-op: For the purposes of this application, the term 'co-op' as used throughout is not intended to refer to the traditional cooperative form of business which is owned by all of its members. A business organization implementing this invention need not be organized as a cooperative. Instead, we use the term 'co-op' to refer to the online manifestation of buying groups who have committed to purchase a certain product within a specified price (i.e., at or below a maximum price). Co-ops are also occasionally refeπed to herein as 'buying groups,' 'buying co-ops' and 'product co-ops. '

Critical Mass: The volume of acceptable offers necessary before any purchase offers will be accepted. The critical mass may be specified by a supplier. It may also be the sales volume at which the starting co-op price is justified.

Cuπent Price: The price stated as current at any given time during the co-op. One significance of the current price is that availability is guaranteed for offers at or above such price after critical mass is achieved.

E-commerce server: Is here used to refer to a specific server software system, residing on a set of CPUs, that is used to send information to the client system(s) and accepting input from said clients for the sole purpose of taking orders, whether they are for co-ops or not.

Ending Price: The price specified at the end of the co-op, which represents the price at which all offers are accepted.

Featured Product: Any product or product variant identified for sale through a co-op. For purposes of this application, the term 'featured product' includes any services which might be identified for sale through a co-op.

HTTP: The Hyper-Text Transfer Protocol.

HTTP server: A specific server software system, residing on a set of CPUs, which is used to communicate with client systems such as HTTP browsers. The HTTP server is only one means of communication between the client and server, and its inclusion in this discussion of our invention is not meant to imply that it is the only means of implementation of the invention.

Offer or Purchase Offer: A binding, non-cancelable offer to purchase a featured product within a price range the maximum of which is specified by the buyer. Each such offer is guaranteed by the respective buyer's credit card at the time it is offered. Making an offer is a condition precedent to joining a co-op. The offer is either accepted or rejected at the close of the co-op.

Price Curve: A description of price as a function, in the mathematical sense, of the number of units. See Figure 6. Product and Product Variant: A product is a set of items for sale, which all has a certain set of significant characteristics in common. For example, a particular brand and style of in-line skates, each having the same characteristics, such as design, brand, color, a left and a right skate sold together, etc. A product variant is a subset of a product. For example, size 5 and size 8 of a particular pair of in-line skates are different variants of the same product. As used herein, a product can be a tangible or intangible object or a service.

Server: The term 'server' is here used to refer to the set of hardware and software systems that are used to implement co-ops in accordance with this invention. These systems are to be distinguished from the client systems that are used by buyers to participate in co-ops. See Figures 4 and 5.

Server process: A computer program that is part of the server software systems, and which executes in its own address space, communicating with other processes via means defined by the operating system(s) of the hardware platforms. Unfortunately, it is necessary to use the term 'process' to describe other things than computer programs executing in their own address space in this application, so care has been taken to always use the term 'server process' when the latter is meant.

Starting Price: The price listed as the current price at the beginning of each co-op.

SUMMARY OF THE INVENTION

In accordance with a first aspect of the invention, a system for an on-line buying co-op includes an e-commerce server data processing system. The e- commerce server data processing system has e-commerce server software executable on the e-commerce server data processing system. The e-commerce server software is configured to define a buying co-op for a product by specifying the product for the co-op, a time interval within which members can join the co-op, the point at which critical mass is reached, any minimum or maximum quantity of the product available through the co-op, and one or more price curves for the featured product. The e- commerce server software is further configured to accept inputs from buyers to take orders for the product. A buyer client data processing system is coupled to the e- commerce server data processing system. The buyer client data processing system includes first client software executable on the buyer client data processing system. The first client software is configured to receive data from said e-commerce data processing system describing the buying co-op for the product, to display the data describing the buyer's co-op for the product on the buyer client data processing system, to receive buyer order inputs for the product and to transmit buyer order inputs for the product to the e-commerce server data processing system.

In a second aspect of the invention, an e-commerce server data processing system for implementing a buying co-op has e-commerce server software executable on the e-commerce server data processing system. The e-commerce server software is configured to define a buying co-op for a product by specifying the product for the co-op, a time interval during which the co-op is available, the point at which critical mass is reached, any minimum or maximum quantity of the product available through the co-op, and one or more price curves for the featured product. The e-commerce server software is further configured to accept inputs from buyers in the form of binding purchase offers to purchase the featured product.

In a third aspect of the invention a process for operating an on-line buying coop includes defining a buying co-op for a product at an e-commerce server data processing system by specifying the product for the co-op, a time interval during which the co-op is available, any minimum or maximum quantity of the product available through the co-op, and one or more price curves for the featured product. Data describing the buying co-op for the product is transmitted from the e-commerce data processing system to a buyer's data processing system. The data describing the buyer's co-op for the product is displayed on the buyer's data processing system. A buyer order input for the product is received on the buyer's data processing system. A buyer order input for the product is transmitted from the buyer's data processing system to the e-commerce server data processing system. The buyer order input is accepted in the e-commerce data processing system to record a purchase offer for the product.

In a fourth aspect of the invention, a process for defining an on-line buying coop for a product in an e-commerce server data processing system includes specifying the product for the co-op. A time interval is specified during which the co-op is available. The point at which critical mass is reached is specified, which is usually a minimum quantity of the product specified either by a supplier or by the entity implementing the invention for a given pπce Any maximum quantity of the product available through the co-op is specified One or more pπce curves are defined for the product available through the co-op In a fifth aspect of the invention, an article of manufacture compπses a computer readable storage medium having stored therein a computer program for operating vaπous product co-ops simultaneously. The computer program includes a first code segment for defining a buying co-op for a product at an e-commerce server data processing system by specifying the product for the co-op, a time interval duπng which the co-op is available, the point at which cπtical mass is reached, usually a minimum quantity of the product for a given pπce, established as above, any maximum quantity of the product available through the co-op, and one or more pπce curves for the featured product. A second code segment is for transmitting data descπbing the buying co-op for the product from the e-commerce data processing system to a buyer's data processing system. A third code segment is for receiving purchase offer input in the e-commerce data processing system to record an offer for the product.

In a sixth aspect of the invention, an article of manufacture compπses a computer readable storage medium having stored therein a computer program for defining an on-line buying co-op. The computer program includes a first code segment which, when executed m a computer, specifies the product for the co-op. A second code segment, when executed in the computer, specifies a time interval for which the co-op is available. A third code segment, when executed in the computer, specifies any minimum or maximum quantity of the product available through the co- op. A fourth code segment, when executed in the computer, defines one or more pπce curves for the product available through the co-op. Introductory Descπption of the Method

A co-op for a gπ en product or product vaπant is defined by placing onto the e-commerce server a set of data descπbmg the co-op in terms of its pπce curve(s), the featured product, the time interval duπng which the co-op is available, the point at which cπtical mass is reached, and the minimum and maximum quantities available Some of these defining properties of a co-op may not be revealed to the buyer

When the co-op is

ailable, buyers enter their offers into the co-op, indicating a maximum pπce at which they will commit to purchase the featured item This may be at the current pπce, or it may be below the current pπce Once the current pπce is justified by the volume of co-op offers, all offers withm a specified reasonable range below the cuπent pπce w ill tπgger a new, lower cuπent pπce for the product

Once the co-op is successful m achieving cπtical mass, offers at the cuπent pπce guarantee availability of the number of items of the product or product vaπant specified m the offer, provided that number does not exceed the difference between the current number of similarly committed units and any maximum number of units available Note that the starting pπce will be established when the co-op is announced, before any offers have been submitted based on the pπce curve and/or other merchandising data Such starting pπce frequently will be based on a minimum number of units that must be ordered for the co-op to qualify for that pπce

A further contingency may be placed on a buyer's offer based on pπce Specifically, should any given buyer indicate that he does not find the cuπent pπce acceptable, but nevertheless wishes to buy it at a lower pπce, his offer is made contingent upon the co-op reaching the lower pπce However, should his offer be deemed to fall withm reasonable range of the cuπent pπce, as defined separately for each co-op, it may be considered part of the market dynamics around the product offered in the co-op As such, it may reduce the pπce of the co-op As more offers are made, and the cuπent pπce drops to a level at or below the contingent pπce specified, the contingency based on pπce is removed Offers may be increased up to the cuπent pπce any time duπng the co-op should buyers wish to improve their chance of success or ensure availability of the item However, offers may not be cancelled nor may buyers reduce their offered pπce

Regardless of the maximum pπce specified within each purchase offer, all members of the co-op get the benefit of the lowest final pπce In addition to seeing the cuπent price go down, the buyers may also be given an indication of how many more participants it would take to get the price down to a specified amount, or potentially the number of acceptable offers necessary to reach critical mass. While every offer might affect the price by small decrements, the price reductions that are sufficiently compelling to encourage buyers to refer others to the co-op might be much greater and will vary from co-op to c-op. Therefore, a co-op is further defined by the 'price curve visibility window,' which is the difference in price that is deemed interesting to a buyer of a given product. The visibility window is in essence the granularity at which the actual price curve is displayed to buyers. Merchandising and yield management personnel will define each co-op by means of data entry. Such data entry is not limited to time prior to the opening of a co-op. The definition of a co-op, including its price curve, is subject to modification during its lifetime. In fact, the ability to modify the co-op definition based on data gathered from offers to participate in a co-op is an essential aspect of the invention. Once a buyer joins a particular co-op, he or she will be permitted to initiate e- mail messages designed to increase buyer volume, thereby further reducing the price available to all. The recipient of such e-mail will be directed back to the specific coop by either a reply function or a link within the e-mail message. If he or she joins, he or she can then send messages to his or her friends and so on. Once a co-op is closed, either because the prescribed time limit is met, or any maximum number of available items is sold, all offers at or above the closing price are accepted and final sales information is communicated to other server processes, which handle the orders' fulfillment via traditional means of hard and digital goods transportation. Buyers who made successful offers are notified of acceptance and product shipment, and those buyers whose offers were not successful are notified of the result.

In addition to participating in co-ops, buyers may utilize an input feature to suggest products or product categories for which they have an interest in a co-op being created. Further information is gathered regarding the buyers preferences including acceptable price, and such person is then notified at the time his or her items are sold by co-op. Other aspects of this function include a focal point or community for buyers to suggest and organize a wide variety of co-ops designed to suit their every need, including the ability to create sufficient demand to support purchases, the specific manufacture of particular products suggested by the various buyers, or the creation of broader interest groups around a category of products.

The attainment of the foregoing and related advantages and features of the invention should be more readily apparent to those skilled in the art, after review of the following more detailed description of the invention, taken together with the drawings, in which:

Introductory Description of the Apparatus

As shown in Figures 4 and 5, merchandising and yield management staff 20 defines a co-op in accordance with the invention using client computer 22 and client software 24, comprised of a set of tools, including but not limited to a pricing tool.

The tools 24 communicate with the server processes 26, including but not limited to the database process, to enter the data relevant to each co-op. The consumer 28 accesses all aspects of the co-op using a client computer 30 running a browser 32 or some other type of client computer program. The client computer program 32 communicates via some means of physical communication layer 34, e g. the Internet, with a server 36, i.e the HTTP server, or a server with similar purpose. The HTTP server 36 further communicates, using public or propπetary protocols, with an e-commerce server 38, which contains the pπncipal software for implementing this invention.

The e-commerce server 38 software and related components is compnsed of a set of server processes 40, a means 42 of communication between the server processes 40, and a database 44 to hold data significant to the process of taking orders and otherwise interacting with the consumer 28. The capabilities of the e-commerce server software and related components extend far beyond the ability to handle co-ops. The present invention is directed to the capabilities that pertain to co-op management. The other capabilities of the e-commerce server 38 software and related components are implemented with software modules and routines known in the art and will not be descπbed beyond that necessary to understand the invention.

As shown in Figure 7, co-ops are pπmaπly manifested by a set of database tables 50 that define the essential properties of the co-ops, a set of program subroutines 52 and server processes 54 and 56 defining the logical processing necessary to manage co-ops and their interaction with buyers, and data contained m the database tables 50 defining the values of the essential properties that define each co-op.

Detailed Descπption of the Method Figure 8 shows a flow diagram of a preferred form of a process in accordance with the invention. Co-op Definition

The steps of the definition of a co-op are as follows

1 The merchandising staff, being generally responsible for product offeπngs, identifies the product to be featured in co-op at 100. They create a new co-op at 102 using a set of computer programs acting as their data entry tools. Numerous co-ops will be featured simultaneously at any given time Essential characteπstics of the coop in this prefeπed implementation are: start time, end time, any minimum number of units offered, any maximum number of units available for sale, starting price, and product cost curve including a price curve visibility window.

2. The co-op receives further definition by having its price curve and price curve visibility window defined at 104 using the pricing tool. The defined co-op is then made available at 106.

3. As data is gathered from buyers, by means of their making offers, the co-op is modified at 108 using the pricing tool, so as to take into account the market data in the definition of the price curve.

Co-op Selection

The steps comprising a buyer's selection of a co-op in which to participate, are as follows:

1. The buyer accesses e-commerce server 38 (Figure 4) at 110, and is presented a number of co-op choices at 112. How the navigation and presentation of general product information pertaining to the co-op is done is not essential to this invention and is done in a conventional manner known to those skilled in the art. The buyer browses all product co-ops in order to choose a particular co-op of interest at 114.

2. The buyer is presented with the following essential co-op information: cuπent price, closing time, next price level (as defined by the price curve visibility window and the price curve), sufficient for the buyer to determine the urgency of an offer.

Offers below Cuπent Price Once a buyer has made up his mind to join a co-op, the decision must be made at 116 to accept the cuπent price, guaranteeing availability once critical mass is achieved, or to make an offer contingent on a lower price range, which may not result in a successful purchase regardless of whether critical mass is achieved. Given the decision to make an offer, the steps are as follows: 1. The buyer enters an offer which specific the price at which he is willing to purchase the product, his credit card number and any other pertinent information at 118.

2. The system acknowledges his offer at 120. 3. The system authorizes his credit card for the maximum price specified in his offer.

4. If the offer is within the range that is deemed reasonable, the cuπent price may be affected as defined by the price curve, and any new price is displayed. 5. If the offer is below what is deemed reasonable, the offer is still recorded, but it is disregarded from the pool of offers allowed to impact cuπent price. The reasonable range may be derived from the price curve or external merchandising factors.

6. Should the cuπent price drop to the level at or below which the offer was made at, such offer is included within the pool of offers to be accepted at close of the co-op at 122 and processed as such. Inventory is allocated to fulfill the order at 126 once the co-op closes at 124.

Offers at Cuπent Price Given the decision to make an offer at the co-op cuπent price, the steps are as follows:

1. The buyer makes a non-cancelable offer to purchase the featured product at the cuπent price at 128.

2. Inventory is allocated to fulfill the order at 126 once the co-op closes at 124. 3. The system acknowledges the offer, and indicates to the buyer that his offer is accepted at 130.

Co-op Close

A co-op will only close if the required critical mass is met. Assuming critical mass is achieved, the steps taken upon closing of a co-op are as follows:

1. The final price is fixed and applied to all offers at or above the final price.

2. All offers meeting the criteria above are accepted and converted to final sales by the e-commerce server, which are then communicated to product supplier and/or a fulfillment representative, which ships the products and charges the buyer's account.

3. All buyers that made successful offers are notified of the success thereof, and notified of the final price.

4. The buyers that made unsuccessful bids are likewise notified of the situation at 132. Volume Building Communication Feature

Upon enteπng a co-op, buyers will be allowed an opportunity to e-mail friends and acquaintances to tell them about the extraordinary deal being offer m the co-op Buyers help themselves to this feature, which is compnsed of the following steps

1 The buyer clicks on specific icon and is asked to supply certain information including the e-mail address of each addressee The quantity of messages sent by any one buyer, and his or her ability to alter text descπbing the e-mail, may be limited

2 The buyer may be able to type a personal message to be included within the fixed text of the message

3 When the buyer indicates his desire to send each message, they are transmitted to the addresses indicated

4 Such messages will provide direct access to the co-op page in question either through a reply function, or via a link in its text

Buyer Suggestions

At any time a potential buyers may utilize a process of suggesting specific products, brands or product categones to be offered in future co-ops Such individual might also specify acceptable pπces at which he or she would be willing to buy the suggested featured product, as well as a wide vaπety of other data This feature is compnsed of the following steps

1 After identifying a specific product or a feature set common to several specific products, the buyer indicates to the system at 134 that he is interested in purchasing the product if it were to be offered at a low pπce under a co-op 2 The buyer might further indicate what pπce he considers to be fair for the product, the brands he finds acceptable in order of preference

3 The system accepts the suggestion at 136, and accumulation and organization of this data by product, feature set, brand, general product category, and/or any number of other cπteria to permit meaningful utilization of the data adds it to its database

4 If and when this data reveals interest sufficient to establish a co-op, the system then notifies the interested buyers via available communication means that the co-op is about to be established

II The invention provides a method and apparatus to permit the quick and convenient formation of any number of special interest groups wherein membership cπtena can be defined in the manner most beneficial to the group For example, those showing an interest in digital cameras, by joining a specific digital camera co-op or otherwise, could be asked whether they'd like to join a special interest group compnsed of camera enthusiasts The formation of such special interest groups is implemented as follows

1 Buyer or potential buyer expresses interest in a certain type of featured product through browsing such product or joining a co-op or otherwise 2 Buyer will be offered an opportunity to join one or more related special interest groups wherein he might be able to maximize access to related information of interest through global aggregation of similarly situated individuals

3 Buyer elects to join one or more such groups

4 The system might notify all members of a given group via available communication means of information of interest, including any future co-op likely to be of interest to such group
