Robert R. Riggs — patent litigation summary

Focus and footprint. Riggs's tracked patent work is narrow: a single matter, MPHJ Technology Investments, LLC v. D-Link Systems, Inc., in which he was lead counsel for the defendant. That case arose out of the well-documented MPHJ "scanner troll" campaign over patents claiming network scanning of documents to e-mail (U.S. Patents 6,771,381; 7,477,410; 7,986,426; 8,488,173; 6,185,590). So the technology at issue is document imaging / networked multifunction office equipment rather than a Wi-Fi, pharma, or software-platform portfolio. Web-searchable firm descriptions place him in a general civil-litigation and business practice at a small Bay Area firm, with intellectual property listed among several practice areas (real estate, construction, land use, design-professional liability) — not a dedicated patent boutique or IP specialty. No other patent matters for him are verified.

Side preference. The data show 0 plaintiff-side and 1 defendant-side appearance: he defends operating companies rather than prosecuting for NPEs/PAEs. Consistent with that, his only tracked case put him opposite MPHJ, a patent assertion entity, on behalf of a networking-hardware maker. One data point is a thin basis for characterizing a career-long preference, and he should not be described as a defense-side patent specialist on this record.

Firm context. He is a founding partner of Katzoff & Riggs LLP, an Emeryville, California firm (formerly listed at Berkeley) with roughly six attorneys, co-founded with Kenneth S. Katzoff; firm materials state both partners have practiced in the Bay Area since 1982, and third-party profiles give a 1991 firm founding date. I found no verifiable prior-firm history for Riggs, and he is not identified as in-house counsel anywhere. I also found no indication that Katzoff & Riggs maintains a standing patent-litigation practice group.

Notable case, PTAB, and credentials. The tracked matter — the MPHJ suit against D-Link — sits inside litigation that generated substantial collateral activity: inter partes reviews of the MPHJ patents filed by Ricoh, Xerox, Lexmark, and HP; an FTC consent order against MPHJ, Jay Mac Rust, and Farney Daniels, P.C.; and state consumer-protection actions (notably Vermont's). That context is verified; whether Riggs participated in any of it, or in any IPR/PGR proceeding, is not. I found no PTAB appearance record for him and no reported verdict, settlement, or Federal Circuit outcome in the D-Link case. Directory listings show him admitted in California in 1984, with a J.D. from Stanford Law School and undergraduate study at Johns Hopkins University. Because the name is common, identity should be confirmed against the Katzoff & Riggs Emeryville partner before relying on this profile.
