David H. Schultz

I'll research this attorney before drafting.

David H. Schultz — patent litigation practice (verification-limited)

Focus areas. The only tracked matter for this attorney is Longitude Licensing Limited et al. v. Apple Inc. et al. (defendant side), an NPE assertion in the semiconductor/memory space. Longitude Licensing is an Irish IP-licensing entity (an IPValue Management affiliate) whose portfolio derives largely from Elpida Memory (DRAM) and SanDisk flash-memory assets; the name matches a long-running dispute over flash-memory system patents (N.D. Cal. No. 3:14-cv-04275, filed 2014) and a 2025 companion action in W.D. Tex. (No. 1:25-cv-00215) asserting semiconductor/memory patents against Apple, Broadcom, and Qualcomm alongside a parallel ITC action. On this record the demonstrated focus is semiconductor/memory and consumer-electronics patent defense, potentially with FRAND/licensing elements. A single appearance is a thin basis for generalizing about broader technology coverage.

Side preference. The tracked data shows 0 plaintiff-side and 1 defendant-side appearance, in a lead counsel role. All verified evidence points to defense of large operating companies against patent-assertion entities; there is no indication of NPE/PAE-side prosecution work.

Firm context. The structured record lists Clifford Chance US. Identity caveat: public sources do not confirm a patent-focused "David H. Schultz" at Clifford Chance. The Clifford Chance partner named David Schultz is David I. Schultz, a New York corporate/private-equity partner (joined 2024 from O'Melveny & Myers; Michigan BA, NYU JD 2001) whose practice is M&A and sponsor transactions, not patent litigation — a different person. Other attorneys sharing the name include David H. Schultz, a New York insurance-defense/commercial litigator at Barry McTiernan & Moore, and David Schultz, a Minnesota IP/product-liability trial lawyer at Maslon. None of these can be reliably tied to the Longitude appearance from the sources reviewed.

Notable cases / results. The Longitude v. Apple litigation produced a pleading-stage ruling (N.D. Cal., Mar. 13, 2015) granting Apple's motion to dismiss the willful-infringement claim with leave to amend, on the ground that alleging knowledge of the SanDisk patent portfolio generally does not establish pre-suit knowledge of the specific patents-in-suit; the case was later the subject of discovery disputes, including an order compelling production to Apple (Nov. 17, 2015). The 2025 W.D. Tex. action against Apple, Broadcom, and Qualcomm was subject to an unopposed motion to stay under 28 U.S.C. § 1659 pending the parallel ITC proceeding. No verdict, appeal, or settlement attributable to this attorney individually could be verified.

PTAB/IPR experience. No IPR, PGR, or other PTAB appearance by this attorney could be verified.

Bar / education. Not reliably sourced for the patent-litigator identity and therefore omitted; no admission or degree should be attributed to this attorney without confirmation.

Verification note: the practice description above rests on the single tracked appearance and the public docket/case record for the Longitude matters. The attorney's identity, firm history, bar admissions, and PTAB activity could not be independently confirmed and should be verified against the firm's own directory or the client before use.
