Plus d'Indexage WWW sans permission de CMGI ?

En janvier 2001 le chef de la société qui a acheté Altavista declare que Altavista detient env 50 brevets sur des methodes de base, sans lesquelles il est impossible d'indexer le WWW, et qu'il va lever une taxe chez tous qui créent des indexes Internet et même intranet et si nécéssaire les attaquer juridiquement, pour achever une valorisation maximale de ces brevets.

Le Début

Le 2000-11-13, CGMI, grande groupe qui possède Altavista et 12 autre sociétés Internet, lancait un communiqué de presse de haut profile, dans lequel il expliqua qu'il possède 38 brevets qui couvrent a peu près toutes les méthodes possibles d'indexation du WWW. Le 2001-111-15, le PDG de CGMI dans un entretien expliqua que CGMI va en bref delai attaquer juridiquement tous ceux qui utilisent telles techniques sans payer, y inclus les mainteneurs de reseaux internes dans les entreprises.

Internet World:
Can we talk a bit about some of the ideas or opportunities that you backed off of because money was an issue this past year?
David Wetherell:
[...]

Even though AltaVista s doing well in the advertising space, we just think that in order to really ensure strong growth they ought to leverage their position in search licensing to a greater extent. And we saw the opportunity to do that because we think it s a big market. They happen to own 38 patents, many of which we think are fundamental in the search area. They were the first to spider and index the Web. And Digital did a good job of recognizing the potential value of that intellectual property. And they were very thorough in filing broad and deep and narrow patents. And we have another 30 patents that are in application. So we believe that virtually everyone out there who indexes the Web is in violation of at least several of those key patents.

IW:
Does that mean you ll pursue that?
DW:
Yes, we will. Coming up in the first quarter of 2001.
IW:
So we may see some lawsuits ...
DW:
If necessary, we will defend it, to the letter of the law.
IW:
Are there any specific examples of the types of patents?
DW:
If you index a distributed set of databases what the Internet is and even within intranets, corporations, that s one of the patents. We did a press release on this with a list of six or ten of the key areas that the patents cover.

->US 5864863
I claim
  1. A system for indexing Web pages of the Internet, the pages stored in computers connected to each other by a communications network, each page having a unique URL (universal record locator), some of the pages including URL links to other pages, comprising: a communication interface for fetching a batch of specified pages of the Web from the computers in accordance with the URLs and URL links;
    a parser sequentially partitioning the batch of specified pages into indexable words, each word representing a portion of one specified page or an attribute of one or more portions of the specified page, the parser sequentially assigning locations to the words as they are parsed;
    a memory storing index entries, each index entry including a word entry representing a unique one of the words, and one or more location entries indicating where the unique word occurs in the Web;
    a query module parsing a query into terms and operators relating the terms;
    a search engine using object-oriented stream readers to sequentially read location of specified index entries, the specified index entries corresponding to the terms of a query;
    and a display module for presenting qualified pages located by the search engine to users of the Web.
->US 5974455
  1. A system for locating Web pages stored on remotely located computers, each Web page having a unique URL (universal resource locator), at least some of said Web pages including URL links to other ones of the Web pages, the system comprising:
    • a communications interface for fetching specified ones of the Web pages from said remotely located computers in accordance with corresponding URLs;
    • a Web information file having a set of entries, each entry denoting, for a corresponding Web page, a URL and fetch status information;
    • a Web information table, stored in RAM (random access memory), having a set of entries, each entry denoting a fingerprint value and fetch status information for a corresponding Web page; and
    • a Web scooter procedure, executed by the system, for fetching and analyzing Web pages, said Web scooter procedure including instructions for fetching Web pages whose Web information file entries meet predefined selection criteria based on said fetch status information, for determining for each URL link in each received Web page whether a corresponding entry already exists in the Web information table, and for each URL link which does not have a corresponding entry in the Web information table adding a new entry in the Web information table and a corresponding new entry in the Web information file.
