Please be apprised of the following Legal Notices: A) Wang contends that its U.S. Patent No. 4, 751,669 ("the '669 Patent") disclosing a "video text" system, is infringed by the following functionality in the Netscape Navigator code: 1) the animated logo and status line indicators --See Claims 1,8 and 9; 2) the "File Save As" function --See Claims 23-27; 3) Bookmarks and Rename Bookmarks in the Properties window --See Claims 20-22; 4) storing HTML, GIF, and JPEG files and adding filename extensions based on mime types (performed in Windows OS) --See Claim 38. Netscape believes the '669 Patent is invalid and non-infringed. Netscape is vigorously defending against Wang's claims. B) Intermind owns pending U.S. patent applications on communications systems which employ metadata ("channel objects") to define a control structure for information transfer. The Netscape code does not infringe as released; however, modifications which utilize channel objects as described by Intermind should be considered carefully. The following is a statement from Intermind: "Intermind's claims fundamentally involve the use of a control structure to automate communications. ...The essence of Intermind's top claim is that two devices sender and receiver have persistent storage, communicate over a network, and exchange a control structure including metadata which describes: 1) what information is to be updated, 2) when to update this information, and 3) how to transfer the updated information. In addition, at least the receiving device must be able to process the metadata in order to perform the update determination and transfer. Any digital communications system which incorporates all of these elements will be covered by Intermind's patents." See Intermind.com. C) Stac, Inc., and its licensing agent Hi/fn, own several patents which disclose data compression methods implementing an LZS compression algorithm, including U.S. Patent Nos. 4,701,745 and 5,016, 009 ("the Stac Patents"). The Netscape Communicator code does not perform compression. If you modify the Netscape source code to perform compression, please take notice of the Stac Patents.
