Received January 16, 2001 From: "Heinze, Bill" Dear Subscribers: In accordance with Section 10 of the Internet Standards Process (RFC 2026), I am writing on behalf of .NU Domain and its affiliate WorldNames, Inc. to notify you of the publication of World Intellectual Property Organization International Publication No. WO 01/90955 A2 entitled "Internationalized Domain Name System with Iterative Conversion." A copy of this document is available at the following website: ftp://ftp.tkhr.com/WO0190955A2.pdf This patent application generally relates to a system, method, and logic for managing data, including a database for implementing a key value operation, such as a DNS resource record lookup, with a key having a predetermined encoding, such as Unicode. Also provided is an iterative converter for iteratively converting the key from each of multiple encodings to the predetermined encoding before performing the key value operation with each converted key. The system may also include a validator for verifying that a syntax of each converted key is valid and a normalizer for normalizing each converted key. We believe that many of the technologies being discussed in this mailing list infringe one or more of the claims starting at page 87 of the attached publication. We would therefore like to propose that you review these claims and contact us immediately with regard to obtaining a license and/or authorized access to WorldNames "MLDNS" multilingual DNS products and services described at the following website: http://www.worldnames.net/MLDNS/default.cfm Please note that failure to promptly obtain the appropriate authorization may subject you and your organization to liability for royalties in the U.S. as of the date that you receive this letter under 35 U.S.C. Section 154(d). Once the application is granted, additional remedies are also available including injunctions, treble damages, and attorney fees. A variety of other presumptions and remedies may also be available in the U.S. and abroad. If you believe that you have a defense to these allegations, such as non-infringement or prior invention, then please provide us with additional information to refute our allegations and avoid further involvement with this matter. Similarly, if you believe that any of the attached claims are not patentable, then please bring them to our attention, along with any relevant prior art, so that we may submit that information to the appropriate patent offices. We are looking forward to hearing from you. Sincerely, William F.
