- 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.
