I'll research this attorney before drafting the summary.

Let me dig into the specific tracked cases and her PTAB experience.

Jennifer Prieb Estremera — Patent Litigation Summary

Focus areas. Estremera's tracked patent matters cluster in computer and electronics technologies rather than pharma or mechanical arts: cloud/enterprise storage architecture (Kove v. AWS), virtualization and capacity-management software (Cirba/Densify v. VMware), video data synchronization and portable-device/touchscreen hardware (VideoLabs v. Apple), and enterprise software, in-memory databases, fault-tolerant systems and multiprocessor cache coherence (Valtrus v. SAP). Firm profiles list her practice more broadly as intellectual property and high-stakes commercial litigation, including trade secrets, trademarks and false advertising; IAM Patent 1000 ranks her for patent litigation and describes her as a trial lawyer who organizes large, complex patent cases.

Side preference. All three tracked appearances are plaintiff-side — VideoLabs (twice, as attorney of record and local counsel) and Valtrus Innovations (of record) — and her publicly reported wins are patent-holder verdicts. Her practice is therefore best characterized as representing patent owners and technology plaintiffs, fitting the NPE/PAE-adjacent posture of clients like VideoLabs, Valtrus/Key Patent Innovations and Kove, rather than a defense-side operating-company docket. Firm marketing notes trial successes for both plaintiffs and defendants, so the tracked data should not be read as an absolute bar on defense work.

Firm context. She is a founding partner of Reichman Jorgensen Lehman & Feldberg LLP (RJLF, founded 2018; Silicon Valley/Redwood Shores headquarters), where sources variously describe her as Managing Partner or Deputy Managing Partner. She was previously at McKool Smith P.C. in Redwood Shores (she appears on a 2019 filing under that firm). Earlier in her career she clerked for the Hon. Edward J. Davila of the U.S. District Court for the Northern District of California.

Notable matters and outcomes. She was on the RJLF trial team that won a $525 million patent-infringement verdict for Kove IO against Amazon Web Services (N.D. Ill., April 2024), which the court supplemented with roughly $148 million in post-trial interest for a total of about $673 million — reported as the largest standing patent victory of 2024. She also helped secure the willful-infringement verdict for Cirba/Densify against VMware in the District of Delaware (reported at roughly $237 million at verdict, with a later damages figure around $84 million; the two numbers reflect different stages of the same litigation, and I could not fully reconcile them from the sources reviewed). In the tracked matters: VideoLabs v. Apple (N.D. Cal. No. 3:23-cv-01307) was dismissed with prejudice by stipulation in October 2023; and Valtrus Innovations v. SAP (E.D. Tex. No. 2:24-cv-00021, Judge Gilstrap) remains active — the Federal Circuit denied SAP's mandamus petition seeking intra-district transfer in April 2025, with RJLF (Matt Berkowitz) arguing for Valtrus.

PTAB / IPR. I found no PTAB proceeding in which she is listed as lead or back-up counsel of record; in the RJLF VideoLabs and Valtrus IPRs that work is handled by other firm attorneys (e.g., Christine Lehman, Patrick Colsher, Matt Berkowitz). Her name does appear on correspondence in at least one IPR exhibit, so she is adjacent to the firm's PTAB practice, but the public record does not establish her as a regular IPR advocate.

Bar and education. J.D., Santa Clara University School of Law (2007); B.A. in Business Administration, Azusa Pacific University (2004). Admitted in California and Kansas, with admissions in the N.D., E.D., C.D. and S.D. Cal., D. Kan. and E.D. Tex.; no USPTO registration number is shown in the sources reviewed.
