David H. Judson

David H. Judson — profile

What the entity is. "David H. Judson" in the case data is a natural person, not a corporation. David H. Judson is a Dallas, Texas–registered patent attorney (USPTO Reg. No. 30,467; State Bar of Texas No. 11047150, admitted 1982) who runs a solo intellectual-property practice, the Law Office of David H. Judson, in Dallas (B.S.E.E. 1978, J.D. 1982, George Washington University). Source: State Bar of Texas / Law Office of David H. Judson listings; USPTO filings. No employee count, revenue or ownership status applies — there is no public company or disclosed parent.

Products / operations. The practice provides patent prosecution, licensing and enforcement services; the firm's USPTO docket covers computer/software arts (CPC subclasses G06F, H04L, G06Q). Judson is also a named inventor in his own right — e.g., U.S. 5,572,643, "Web browser with dynamic display of information objects during linking" (filed Oct. 19, 1995; issued Nov. 5, 1996), covering display of ads/messages in a browser while a link loads. He holds no operating business in the case data; he is best characterized as an individual non-practicing patent asserter (the Stanford NPE Litigation Database classifies the case as "Non Practicing Entity," asserter category "Individual").

Litigation posture. One tracked case, as plaintiff only (1 plaintiff / 0 defendant). He sued Infonautics, Inc., No. 1:01-cv-10464 (D. Mass., filed Mar. 19, 2001; terminated June 4, 2001 — roughly eleven weeks, consistent with early resolution). The database records five asserted patents: 5,572,643; 5,722,067; 5,737,619; 6,157,823; and 6,185,586. No declaratory-judgment counterclaim is recorded. The venue is Massachusetts, not the plaintiff-friendly Eastern District of Texas.

Context. Infonautics (Wayne, PA; founded 1992; NASDAQ-listed 1996) was an online information-services company (Electric Library, Encyclopedia.com, CompanySleuth) that sold its school/library business to Bell & Howell's bigchalk.com and was acquired by Tucows via reverse merger in August 2001 — i.e., it was a small-cap operating company, not a patent holder, when sued. Judson separately appears as counsel of record for patent-holding entities such as Message Notification Technologies, LLC (IPR2015-00258), indicating continuing involvement in patent monetization work.
