Andrew Henderson

I'll research this attorney's background before drafting the summary.

Let me verify his firm bio and PTAB/IPR activity.

Let me check the firm bio and PTAB filings directly.

Specialty / focus. Andrew Henderson (also listed in firm materials as "Drew Henderson") is a patent litigator at Irell & Manella whose tracked work is concentrated in semiconductor memory technology. The patents in his tracked cases cover DRAM memory modules and related architecture — LRDIMM, DDR4/DDR5 RDIMM and MRDIMM, NVDIMM/NAND flash, and on-module power management. Both tracked matters arise from the long-running Netlist–Micron–Samsung memory litigation, so the asserted technology is computer memory and the JEDEC/standard-practice issues that surround it (RAND, essentiality, willfulness) rather than Wi-Fi, pharmaceuticals, or mechanical arts. I found no publicly available firm bio text describing a broader technical practice, so his technology profile here rests on the docket record.

Side preference. His tracked appearances are 1 plaintiff-side and 2 defendant-side, but the underlying alignment is consistent: in every tracked matter the client is Netlist, the patent owner, either as plaintiff asserting patents (Netlist v. Samsung) or as defendant in a declaratory-judgment action brought by an accused infringer (Micron v. Netlist, D. Idaho No. 1:24-cv-00001, where he filed an appearance and a motion to stay on Netlist's behalf, and the related D. Del. No. 1:26-cv-00246 transferred from E.D. Tex.). He is therefore best characterized as asserting-side counsel for a patent holder in memory-patent campaigns, not as a defense-side litigator for operating companies, notwithstanding the two "defendant" entries in the tally. His role in the larger teams appears to be as a supporting/prep team member rather than lead trial counsel.

Firm context. He is at Irell & Manella LLP (Los Angeles, and the firm's Century City/Washington offices appear as of-counsel addresses in filings), where he has appeared since 2022. No prior firms surfaced in the tracked data or in public records I could verify.

Notable matters and PTAB. Headline results in his case cluster: Irell's $445 million willful-infringement jury verdict for Netlist against Micron (E.D. Tex., May 23, 2024) and the Netlist v. Samsung verdicts ($303.15 million in April 2023; $118 million in November 2024), with Netlist v. Samsung later recognized by Managing IP as an "Impact Case of the Year." Firm announcements list him among the Micron trial team and as "a key part of the prep team" for Samsung. On PTAB work: the E.D. Tex. Samsung litigation was heavily affected by PTAB final written decisions invalidating asserted claims, and his name appears copied on correspondence in the Samsung v. Netlist proceeding PGR2025-00071; however, I could not verify from the sources reviewed that he is counsel of record in any IPR or PGR petition, so treat any IPR/PGR experience as unconfirmed.

Bar / education. Admitted to the State Bar of California on December 12, 2022 (No. 347596), active and with no record of discipline; J.D., USC Gould School of Law (per the State Bar profile). He is admitted pro hac vice in E.D. Tex. and D. Idaho matters; no USPTO registration was found.

Note on sourcing: the State Bar profile for Andrew Henry Henderson lists dhenderson@irell.com and the Irell bio page for "Drew Henderson," and firm case announcements and docket signatures use both names interchangeably; I have treated them as the same attorney. Details such as exact academic honors and prior employment were not verifiable and have been omitted.
