Timothy R. Shannon — Patent Litigation Practice Summary
Specialty and technology focus. Shannon maintains a national patent litigation practice out of Duane Morris's Boston office, with an emphasis on electronics and semiconductor-adjacent technologies: Wi-Fi/RF front-end module (FEM) chips, computer chip manufacturing and packaging, software (including integrated development environments), LED lighting, and medical devices/life sciences (stem cells, genetically modified animal models, biopharmaceuticals). His Yale undergraduate degree is in mechanical engineering, and his docket reflects a mix of electrical/electronics work and bench-science matters.
Side preference. He works both sides but is defense-weighted. Of the four tracked appearances, three are defendant-side roles and one plaintiff-side. His defense work is almost entirely for operating companies and product manufacturers (Kangxi Communication and its U.S. subsidiary Grand Chip Labs, Green Creative, Kind LED Grow Lights, Legrand, The Jackson Laboratory), frequently in suits brought by NPEs/PAEs (Lexington Luminance, SemiLED Innovations, Prosperina Ventures, Protect Animals With Satellites). He also brings affirmative claims for operating-company clients — e.g., OnPoint Systems' multi-patent GPS-enabled pet-tracking suit in E.D. Tex. and Current Lighting Solutions (the former GE commercial/industrial lighting business) against Signify. He is not an NPE-side filer.
Firm context and notable matters. He has been a partner in Duane Morris's Intellectual Property Practice Group since November 2021, joining from Verrill Dana LLP (partner 2012–2021; counsel 2010–2012); before that he was an associate at WilmerHale (2002–2010). His most prominent tracked matter is the cross-border Skyworks v. Kangxi dispute, spanning ITC Inv. No. 337-TA-1413 and parallel C.D. Cal. actions (8:24-cv-00974 / -00976). He co-led the Kangxi defense team with Duane Morris & Selvam partner Li Zheng; in January 2026 the ALJ issued an initial determination of no infringement on U.S. Patent Nos. 9,917,563 and 8,717,101, with the remaining three asserted patents having been withdrawn by Skyworks during discovery. In April 2026 the ITC terminated the investigation on a withdrawal agreement, and Skyworks dismissed the stayed California case — reported as an unconditional withdrawal. Other representative work includes Current Lighting's multi-forum dispute with Signify and the Alzheimer's-model mouse litigation for The Jackson Laboratory.
PTAB/IPR experience. He appears in PTAB proceedings on both sides of the caption, in parallel with district court and ITC matters. As patent owner's counsel for OnPoint Systems he handled IPR2021-01483 (and related IPRs filed by Protect Animals With Satellites); the final written decision held all challenged claims of U.S. Patent No. 9,848,295 unpatentable and denied the revised motion to amend — an adverse outcome for his client. As petitioner's counsel for Kangxi he was involved in a series of IPR petitions against Skyworks patents (including U.S. Patent Nos. 8,717,101; 7,409,200; 9,450,579); several were denied institution on discretionary/"settled expectations" grounds, and the Federal Circuit denied Kangxi's mandamus petition seeking to overturn that practice (In re Kangxi Communication Technologies, No. 26-115, Fed. Cir. Feb. 24, 2026, nonprecedential). His firm profile states he "has experience in PTAB proceedings and the International Trade Commission," which the docket corroborates.
Bar and education. Admitted in Massachusetts and Maine; J.D., Harvard Law School (cum laude, 2002); M.St., University of Oxford (1997); B.S. (Mechanical Engineering) and B.A. (History), Yale University (1994).
Sourcing note: Firm history, education, admissions, and representative matters come from Duane Morris's attorney profile and its November 2021 lateral-hire announcement; the ITC/Kangxi outcome is documented in Duane Morris client alerts, ITC/PACER dockets, and Kangxi's Shanghai Stock Exchange disclosures (announcement Nos. 2026-004 and the January 2026 update). The OnPoint IPR and Kangxi v. Skyworks IPR outcomes are drawn from PTAB final written decisions, institution decisions, and Federal Circuit orders. One third-party directory (Super Lawyers) lists his law school graduation as 2001, which conflicts with the firm's "J.D. 2002" statement.
