Justin L. Constant — Patent Litigation Practice Summary

Focus areas. Constant is a Houston-based IP litigator and registered patent attorney whose docket skews toward semiconductor and computer-hardware patents — multicore processor architecture, cache coherency, and processor power management — plus a substantial life-sciences/diagnostics component. His tracked work includes several cases involving Daedalus Prime LLC (asserting former Intel processor patents) and the Guardant Health v. Tempus AI dispute over cell-free DNA liquid biopsy and cancer-detection technology. His technical background (B.S.E., Cornell) and USPTO registration are consistent with the hardware-heavy portion of that practice. Venues are concentrated in the Eastern District of Texas, District of Delaware, and the PTAB.

Side preference — both, with a recent plaintiff-side tilt. The tracked appearance data shows 2 plaintiff-side and 1 defendant-side matters, and the identifiable cases fit that split. On the plaintiff side he has represented Daedalus Prime LLC — a patent assertion entity — against MediaTek (E.D. Tex., No. 2:24-cv-00235, eight patents) and against Samsung (E.D. Tex., filed Sept. 2022), and he moved pro hac vice for Guardant Health, an operating company, as plaintiff in Delaware. His defendant-side experience comes mainly from his prior firm, where he represented Intel in PTAB challenges. This is not a single-side practice: he has worked both asserting patents for NPE/PAE clients and defending operating companies.

Firm context. Constant is presently with Blue Peak Law Group LLP, a Houston IP litigation boutique; Super Lawyers lists him there in IP litigation, with Rising Stars selections from 2016 through 2024. Before that he was a litigation associate at Weil, Gotshal & Manges LLP in Houston (the State Bar directory and Martindale both reflect that affiliation), where his work included Weil's Intel patent matters. There is no indication he has held an in-house position. No published Blue Peak attorney biography for him was located in connection with this summary, so his current title at the firm (partner vs. counsel) is not verified.

Notable matters and PTAB experience. The most prominent tracked matters are Guardant Health, Inc. v. Tempus AI, Inc. (D. Del. No. 1:24-cv-00687, consolidated with No. 1:25-cv-01013), in which the court denied Tempus's § 101 motions to dismiss on August 26, 2026, with a Markman hearing set for October 2026 and trial in 2028; and Daedalus Prime LLC v. MediaTek Inc., where Judge Gilstrap granted MediaTek's partial motion to dismiss the § 271(f) and pre-suit willfulness allegations on March 12, 2025 — an adverse ruling for the plaintiff side. On the PTAB side, Constant appeared as backup counsel for Intel in Intel Corp. v. Alacritech, Inc. (IPR2017-01406) and in Intel/Cavium IPR2018-00234, and he is a registered practitioner (Reg. No. 66,883). Notably, the Daedalus Prime assertions have generated parallel IPR petitions by MediaTek and Arm (e.g., IPR2025-00243, IPR2025-00207); his specific appearance in those proceedings could not be verified from available records. The Law360 attorney profile lists nine matters for him at Blue Peak, while the structured case list supplied here contains only three entries with placeholder names — so the counts above may understate his overall docket.
