Joshua Hain Park

I'll research this attorney before writing the summary.

I found the attorney is in Fish's Houston office and may have a prior firm. Let me dig further.

Let me get the full Fish bio and verify the tracked case and prior firm.

Professional Summary — Joshua Hain Park

Specialty / focus areas. Park's practice is patent, trademark, and trade secret litigation in U.S. district courts, with the firm bio emphasizing extensive work in the Western and Southern Districts of Texas and appearances in Delaware and the Northern District of California. His technical center of gravity is electro-mechanical technology, particularly oil and gas — downhole tools and electric hydraulic fracturing systems — with additional casework in point-of-sale systems, erosion prevention systems, and industrial food manufacturing. Before law school he worked on high-purity gas systems for biopharmaceutical manufacturing and on thermal airflow configurations for enterprise servers, which is an engineering background rather than evidence of a pharma or life-sciences litigation practice. Notably, his public materials do not show Wi-Fi/standards-essential-patent work, and the one currently tracked matter involves consumer software/UI design patents.

Side preference. The tracked data show a consistent defense posture: 1 appearance, all on the defendant side, as lead counsel. That is consistent with his broader reported docket — Law360's attorney page for him lists additional matters including JUUL Labs v. NJOY (D. Ariz., 2025), Haptic, Inc. v. Apple (N.D. Cal., 2024), and GMR Safety, Inc. v. Systems, LLC (N.D. Ill., 2024, trademark) — in each of which the Fish-side client appears to be the accused infringer or defendant. Earlier, at Patterson & Sheridan, he represented patent owner U.S. Well Services against Halliburton in W.D. Tex. litigation and a related IPR, i.e., again the defending party. Nothing in the sourced record indicates plaintiff-side or NPE/PAE prosecution work; the pattern is defense of operating companies. Treat the supplemental Law360 matters as reported docket listings rather than confirmed outcomes.

Firm context and notable matters. Park is at Fish & Richardson in Houston (the firm's Houston office is its Texas patent litigation hub alongside Dallas/Austin). He was previously at Patterson & Sheridan LLP in Houston, where he appeared as counsel of record in U.S. Well Services, LLC matters in W.D. Tex. (No. 6:21-cv-00367) and in IPR2021-01032, Halliburton Energy Services v. U.S. Well Services — confirmed PTAB involvement, on the patent-owner side. His most prominent tracked case is Peer Global Inc. v. Apple Inc., No. 7:26-cv-00033 (W.D. Tex., filed Jan. 29, 2026, Judge David Counts), in which Peer Global asserts three patents against Apple over the "Liquid Glass" iOS interface design; Park is listed as lead counsel for defendant Apple, and Fish colleagues (e.g., Joy B. Kete) also appear. Apple has separately petitioned for IPR against Peer Global (IPR2026-00437, filed Aug. 2026), consistent with the firm's parallel district-court/PTAB strategy, though Park's personal role in that petition is not confirmed. No verdicts, settlements, or Federal Circuit results in his matters are verifiable from the sources retrieved.

Bar / education. Not reliably sourced in the materials retrieved; Fish's bio page excerpt and search results did not disclose his J.D. institution or bar admissions, so I've omitted them rather than guess. He should not be confused with Fish colleagues Joshua A. Griswold (Dallas managing principal) or Joshua Carrigan, who are different attorneys.
