       DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS 
       [0031]    The matters exemplified in this description are provided to assist in a comprehensive understanding of exemplary embodiments of the invention. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the claimed invention. Also, descriptions of well-known functions and constructions are omitted for clarity and conciseness. 
         [0032]    The Netword™ system (“System”) utilizes a Netword™ (“leased term”), as points-of-entry in keyword searches for users of the System. The System then delivers to users both the search results and a message, which relates to the Netword™. Messages can be made available to a user, as seen in  FIG. 6 , by clients who lease the rights to the Netword™ on an exclusive basis within specific geographic zones, as seen in  FIGS. 1   b  and  2   a.  The Netword™ may be leased for an unspecified time period or a specified time period. According to exemplary embodiments, a client may be any entity that is interested in leasing a term from the System where the client can be individual, an organization, an information provider and/or an advertiser. For example, an advertiser can be a client that is interested in leasing a word from the System for providing an advertisement. According to exemplary embodiments, a user may be an entity that is using an electronic document (such as a browser) with the System associated with the electronic document. For example, a user can be a computer user that is using an Internet browser (or any electronic document) with a plug-in set-up for searching for words by utilizing the System. A user can enter a keyword into the System (ie., via a toolbar plug-in) and the System will determine if the user&#39;s keyword matches a Netword that is stored in the System memory, and if there is a match, then a search result for the user&#39;s keyword is presented to the user on at least one platform associated with the Netword along with one or more of the client&#39;s message/communication associated with the Netword. 
         [0033]    According to exemplary embodiments an electronic document can include a browser (such as any commercially available Internet and Intranet browser), a word processor, an image processor, a pdf viewer and/or any other electronic document capable of presenting textual, graphical and/or audio data to a computer user. A client can be their own lexicographer. 
         [0034]    According to exemplary embodiments a word may be one word and/or a phrase comprising a plurality of words, terms and/or letters. The word may or may not appear in a dictionary with a definition. For example, a client may create a word with one or more letters that can serve as the Netword™. A client can be their own lexicographer. 
         [0035]    According to exemplary embodiments a keyword may be one word and/or a phrase comprising a plurality of words, terms and/or letters. The keyword may or may not appear in a dictionary with a definition. For example, a client may create a keyword with one or more letters that can serve as the Netword™. A client can be their own lexicographer. 
         [0036]    The System provides clients with the ability to have their specific messages displayed alongside keyword search results for a combination of geo-targeted areas. For example,  FIGS. 6 and 10  show exemplary results of when an advertiser leases a Netword™, then the search results are provided to a user in the bottom portion of a browser along with the advertiser&#39;s advertisement on the top portion of a browser. According to another embodiment,  FIG. 11  shows results of when the advertiser leases a Netword™, then the search results are provided to a user in one browser and the advertisement is provided in a separate browser window. 
         [0037]    According to exemplary embodiments, a message can be an object that is linked to another electronic document via a hyperlink. The message can be a version of a web-site of the client, providing similar experience to a user as if the user was using the client&#39;s web-site, as shown in  FIGS. 6 ,  10  and  11 . The message can be any object (including a graphical, text or non-graphical object) that is linked to another electronic document via a link, as shown in  FIGS. 6 ,  10  and  11 . The link can include a hyperlink to another object (for example, a link to another electronic document) and/or a Uniform Resource Locator (“URL”) to another file, object or an electronic document. According to an alternative embodiment, the message can be an object (including a graphical, text or non-graphical object) that does not contain any links, as shown in  FIG. 13 . The message can present any information that the client chooses, including advertising data, current events data and informational data. 
         [0038]    For example, in  FIGS. 10 and 11 , upon the user entering a search request for the Netword™ “coffee” into the System, the System provides the search results to the user along with an advertisement for Starbucks Coffee™. The advertisement presented to the user is Starbucks&#39; web site directly. The user can freely interact with Starbucks&#39; web site as if the user had initiated communication with the web site for Starbucks by entering the URL for 
         [0039]    Starbucks in an address box of a browser.  FIG. 10  shows an example of a zip code level Netword™ search result where the advertisement is presented in the top portion of the browser and the Internet keyword search result is presented on the bottom portion of the browser.  FIG. 11  shows an example of a state level Netword™ search result where the advertisement is presented in a first browser window and the search Internet keyword search result is presented in second browser window. 
         [0040]    According to another example, as shown in  FIG. 13 , upon the user entering a search request for the Netword™ “auto upholsterer” into the System, the System provides the search results to the user along with an advertisement/coupon/message for Joey M&#39;s Upholsterers. The message presented to the user is not linked to anything else.  FIG. 13  also shows a Netword™ search result where the advertisement/coupon/message is presented in a first browser window and the search Internet keyword search result is presented in second browser window. 
         [0041]    According to an exemplary embodiment, the System for national, regional and/or state geo-targeting can be augmented to include zip-code for smaller geo-targeting (see  FIGS. 1   a ,  1   b ,  2   a  and  2   b ). The addition of zip-code level geo-targeting (alone or in combination with national, regional and/or state level) allows small and large local clients (such as advertisers) within the System, to take advantage of the Internet to market their message (for example products, services and information) to targeted users who will be the recipient of clients&#39; message (for example, small local businesses can advertise to potential customers in a local zip code). With this System, a client that leases a Netword™ within a specific zip-code (alone or in combination with national, regional and/or state level) will have exclusive rights to associate and distribute their message alongside keyword search results for that zip-code. 
         [0042]    As shown in an exemplary embodiment in  FIGS. 2   a  and  2   b , the available zip codes are presented to a client at the time of ordering a leased word along with the population in that zip code, from a database where zip code data is periodically updated based on population counts to reflect a change in population, and clients can choose which zip codes they would like to target. 
         [0043]    According to exemplary embodiments, the pricing structure for national, regional and state leased words is separate from that of zip-code level leased word. The higher level leased words are priced based upon at least four factors which are co-multiplied, as follows: 
         [0044]    1) The selected state, regional, or national geo-target. Factors are determined here based upon population. The larger the population, the higher the factor; 
         [0045]    2) Type of search platform or groupings of platforms. Platforms are either search engines (Google, Yahoo, etcetera) or e-commerce websites (E-bay, Yahoo Shopping, etcetera). Factors here are determined based upon search or e-commerce market share; 
         [0046]    3) Number of web browser plug-ins downloaded. The more Users who download the plug-in, the higher the factor; and 
         [0047]    4) Keyword search popularity. The greater the number of searches nationally per month for a specific keyword, the higher the base price factor for that keyword. This data can pulled from any third party sources that provide statistics for web behavior, for example, www.wordtracker.com and/or www.overtire.com. 
         [0048]    According to exemplary embodiments, as shown in  FIG. 2   c , Zip-code level geo-targeted Networds are priced based upon a pricing tier determined by population within the specific zip code. This information can be pulled from a commercial database which obtains its information from one or more third party sources. For example, the System can obtain information relating to zip codes and population from The U.S. Census Bureau and/or other third party sources. 
         [0049]    According to an exemplary embodiment, Networds can leased for certain periods of time, after which then cease being leased words. 
         [0050]    According to an exemplary embodiment, as shows in  FIG. 4 , in order for a user to use the System, he or she acquires a web browser plug-in onto his computer. Upon installation of the plug-in, the user inputs a short profile which allows the System to identify the geo-target for the user. For example, as shown in  FIG. 5 , after successful installation of the plug-in, the user is presented with the Agent Setup window. The user can enter their Postal Code, Country Code, Distance and Language. The System interprets the Postal Code as the user&#39;s zip-code. Thereafter, the zip code is identified and associated with the browser of that user&#39;s computer until the user changes it. In this example, the System also automatically associates the browser with the geo-targets “California”, “Western United States Region”, and “U.S. National”. After initialization, the user can conduct searches, via the System, on almost any platform (search web site and e-commerce web sites that deliver search results) and additionally resolve clients&#39; messages. 
         [0051]    According to exemplary embodiments, as shown in  FIGS. 1   b  and  2   a,  the System works in conjunction with the identified platform(s) (for example, search engines and e-commerce web sites) capturing search requests from the user and then displaying clients&#39; message (for example, an advertisers&#39; advertisement) along with the user&#39;s requested search result.  FIGS. 6 and 10  show exemplary results of zip code level Networds where the advertisement is presented in the top portion of the browser and the keyword search result is presented on the bottom portion of the browser.  FIG. 11  shows an exemplary result of state level Networds where the advertisement is presented in a first browser window and the keyword search result is presented in a second browser window. 
         [0052]    According to exemplary embodiments, the message can either be linked to another file, another electronic document or be a message that contains no links. If the message contains a link, the link can include a hyperlink to another object (for example, a link to another electronic document) and/or a Uniform Resource Locator (“URL”) to another file, object or an electronic document. A message can be linked to any object that the client specifies (for example, an advertiser client may link the message to their web site or any other web site) such that users can click on the message and they will be navigated directly to the client&#39;s specified web site. Also, the message that is presented to the user can be the client&#39;s web site itself or a similar representation of the client&#39;s web site such that the message can provide the user with an experience similar to an experience as if the user was presented with the client&#39;s web-site itself. For example, as shown in  FIGS. 10 and 11 , upon the user entering a search request for “coffee” into the System, the System provides the search results to the user along with an advertisement for Starbucks Coffee™. The advertisement presented to the user is the Starbucks&#39; web site directly. The user can freely interact with Starbucks&#39; web site (in the advertisement window) as if the user had initiated communication with the web site for Starbucks. The Netword™ “coffee” is associated, within the System, with the advertisement for Starbucks and anytime a user queries the Netword™ “coffee” within a specified geo-targeted area, they will be presented with the message from Starbucks alongside the search results.  FIG. 10  shows exemplary results of zip code level Networds where the advertisement is presented in the top portion of the browser and the Internet keyword search result is presented on the bottom portion of the browser.  FIG. 11  shows an exemplary result of state level Networds where the advertisement is presented in a first browser window and the search Internet keyword search result is presented in a second browser window. 
         [0053]    Zip-code level geo-targeted (alone or in combination with national, regional and state level) leased word provides the benefit to clients by presenting users with search results along with targeted and highly appropriate message results based upon the zip code associated with the browser, which can be related to the user&#39;s geographic location zip code (alone or in combination with national, regional and state level), as shown in  FIGS. 6 and 10 . The user has the option of entering any zip code they choose using the Agent Set-Up feature, as shown in  FIG. 5 . For example, the user may physically be located in 90210, but may be interested in seeing results for 20036. In which case, the user can enter 20036 into the Agent Set-up window and the results will be presented with messages that are associated with the zip-code 20036. This provides users, who can be potential customers for the clients, to be delivered highly geo-targeted, maximum value messages. 
         [0054]    An aspect of exemplary embodiments of the present invention, as shown in  FIGS. 1   b ,  2   c,    3  and  12 , is to provide a method for providing exclusive rights to use of a leased word, the method comprising providing an electronic document to a client for placing an order for leasing a word. The method includes receiving a word from a client for leasing, receiving a URL from the client for associating with the word if the client provides a link to associate with the message, presenting a plurality of available geo-target areas to a client, wherein the client can select at least one geo-target area for associating with the word, receiving at least one selected geo-target from the client, presenting one or more platforms to the client for capturing user&#39;s searching for a keyword, determining the clients&#39; platform(s) and associating the platform(s) with the word, calculating a pricing structure for leasing the word associated with the selected geo-target areas, determining the availability status of the word, wherein the availability status is either available, lease pending or leased, for the selected geo-target area, displaying the availability status and a price structure of the word associated with the selected geo-target areas, displaying a purchase order status to an advertiser for the word associated with the selected geo-target areas, receiving a purchase order from a client for leasing the available word in the selected geo-target area, storing a relationship for the leased word with the selected geo-target areas, and updating the availability status of the leased word. 
         [0055]    According to exemplary embodiments, if the System does not find an advertiser client that matches a keyword, then the plug-in expands the single search result window without a message and presents the search result to the user. 
         [0056]    According to an exemplary embodiment, to setup the System, the user enters the word leasing entity web site Uniform Resource Locator (“http://www.netword.com”&gt;) into the address block of a browser, download and install a plug-in for a supported browser by downloading the corresponding installation package. Alternatively, the plug-in for using the System may also be provided to the user using compact discs, floppy disks, flash memory devices and/or any other device or channels for distributing software to a user (it is contemplated that broader, additional distribution channels may be used for acquiring the plug-in software). The plug-in for using the System may also be pre-installed onto a user&#39;s computer. The System, when running on a user&#39;s browser, as shown in  FIG. 4 , allows the altering of location settings for the plug-in, using a set-up window, as shown in  FIG. 5 . These settings include, but are not limited to, postal code (which can be interpreted by the System as zip code), country code, distance and language, for setting the user&#39;s geo-target. 
         [0057]    According to exemplary embodiments, the function of the plug-in is to track the moment when a user retrieves data on the Internet using certain search engines or commercial web sites and, on the basis of target data, to return additional results from the Advertiser web site. The leased word plug-in system takes advantage of certain technologies. For example, for the Internet Explorer browser, leased word uses ActiveX, COM and XML. For the Mozilla browser, leased word uses Framework “Wise”, Dynamic HTML and CPDF library. The plug-in interfaces for all supported browsers and/or electronic documents can be similar. 
         [0058]    According to an exemplary embodiment of the present invention,  FIG. 3  illustrates a Netword™ order status describing a summary of a leased word purchase order for an advertiser. The order status illustrates a purchase order presented to the advertiser for the Netword™ associated with the selected geo-target areas and the selected platforms. The order status also illustrates the price of the leased word with the selected geo-target areas and platforms, along with the total for the order.
