Perilla Knox & Hildebrandt

Perilla Knox & Hildebrandt LLP (PKH) is an intellectual property boutique law firm with offices in Atlanta, Georgia, and Boca Raton, Florida. The firm is consistently recognized in the legal industry, earning Tier 1 rankings in "Litigation - Intellectual Property" and "Patent Law" for Atlanta in the 2026 edition of Best Law Firms®, along with national recognition for "Patent Litigation." PKH prides itself on providing sophisticated legal counsel with the responsiveness of a smaller firm.

The firm's patent litigation practice spans a diverse range of technologies, including power equipment (multi-fuel generators, carbon monoxide detection), consumer products (strollers), computer systems, software, semiconductors, and medical devices. PKH primarily serves as defense counsel for operating companies, with nine of its twelve tracked appearances on the defendant side. This focus is consistent with its stated mission of safeguarding innovations for operating companies and universities.

PKH has achieved notable results in complex patent disputes. The firm successfully defended Champion Power Equipment Inc. in 13 inter partes review (IPR) proceedings, securing victories in all 11 institution decisions received, including nine outright denials and two initial PTAB institution decisions that were overturned by USPTO Director John Squires due to inconsistent claim constructions. In Baby Jogger, LLC v. Monahan Products, LLC (d/b/a UPPAbaby), involving convertible strollers, PKH successfully opposed a motion for summary judgment based on equitable estoppel, allowing the patent infringement action to proceed.

The firm maintains a robust PTAB and IPR practice, frequently representing patent owners in post-grant proceedings. This practice has demonstrated significant success, particularly in defending against IPR challenges by leveraging strategic arguments regarding claim construction consistency.

Key partners driving the firm's patent litigation success include Joseph W. Staley, who has appeared as lead counsel in all 12 tracked cases and is recognized by Best Lawyers® in "Litigation - Intellectual Property" and "Patent Law." Scott P. Amy, with nine tracked appearances, is also a recognized partner in "Litigation - Intellectual Property" and "Litigation - Patent" with over 20 years of experience, including PTAB proceedings. Thomas Finch, appearing in nine tracked cases, is an associate specializing in patent enforcement before district courts, the Patent Trial and Appeal Board, and the U.S. Court of Appeals for the Federal Circuit, bringing a background in software engineering.
