Top 10 Best Intellectual Property Litigation Services of 2026

Sterne, Kessler, Goldstein & Fox supports patent infringement litigation by building case theory around claim interpretation, prior art themes, and damages framing. Litigation work typically includes drafting infringement and invalidity positions, coordinating expert reports, and preparing trial and motion filings around defined legal and technical issues.

A clear tradeoff is narrower subject breadth outside core IP disputes, so teams with heavy non-IP claims may need additional co-counsel coverage. Sterne, Kessler, Goldstein & Fox fits best when a patent case needs tight technical-to-legal translation and expert coordination across the full lifecycle, from early strategy through dispositive motions and hearing practice.

Knobbe Martens is particularly strong when accused products require engineering-level claim construction work and when disputes turn on technical proof in discovery and source material review. The firm’s litigation workflow emphasizes contention mapping to drive motion practice, while expert work is integrated with infringement theory and damages positioning. RBAC, audit logs, or automation tooling are not offered as differentiators for litigation execution, but the firm does show consistent internal governance through role-based team composition across case phases.

A tradeoff is that the firm’s technical depth can increase coordination overhead for matters with limited technical documentation or short timelines. Knobbe Martens is a good fit when the case must be built to withstand claim construction scrutiny and evidentiary challenges in electronically stored information review, not when the dispute is primarily low-technical contract enforcement.

Bird & Bird operates as an IP-focused litigation counsel, with experienced advocates for patent infringement litigation, trademark infringement litigation, and copyright infringement litigation in addition to trade secret misappropriation disputes. Case handling typically spans pleadings, jurisdiction and procedural strategy, evidence planning, and witness preparation, with expert coordination built into the workflow. Engagements often require tight alignment between infringement theory, invalidity arguments, and damages framing so that discovery requests and expert reports do not conflict.

A practical tradeoff is that the firm’s specialist structure can require more lead time for internal conflict checks and expert resourcing than general commercial litigation firms. Bird & Bird fits best when the dispute timeline demands structured preparation for electronically stored information, protective orders, and litigation holds before discovery accelerates. It also fits situations where parallel proceedings require coherent positioning across different procedural stages.
