What Hamilton, Brook, Smith & Reynolds, P.C. does

Hamilton, Brook, Smith & Reynolds, P.C. (HBSR) is a Massachusetts-based intellectual property law firm founded in 1980 and operating as an independent professional corporation with offices in Lincoln, MA (headquarters) and Boston, MA (Seaport Innovation District). The firm delivers a full suite of IP legal services including patent preparation and prosecution, trademark registration and prosecution, IP litigation in federal courts, post-grant proceedings (IPR, TTAB oppositions), copyright registration, IP due diligence and audits, licensing, trade secrets, open source software counseling, design patents, domain name disputes, and strategic IP counseling. One hundred percent of the firm's work is IP-related, distinguishing it from general practice competitors, and the technical bench spans biotechnology, pharmaceuticals, medical devices, chemistry, software, AI/ML, blockchain, telecommunications, optics, nanotechnology, and electrical/chemical/mechanical engineering, supported by a workforce in which 50% of legal staff hold advanced degrees and 41% of professional staff are women.

The firm serves a diversified client base anchored in life sciences and biotechnology companies, with additional segments in technology companies (including AI and blockchain), research universities, and startups and emerging growth companies. Customers range from global pharmaceutical enterprises to mid-market technology firms to early-stage startups, with engagements including patent portfolio strategy, freedom-to-operate analyses, M&A due diligence, and technology transfer. Marketing and business development are conducted through industry events, webinars, professional association participation (Boston Patent Law Association, LES, Medical Development Group of Boston, German-American Business Council), and thought-leadership content, consistent with a relationship-driven, referrals-and-reputation GTM motion.

The revenue model is professional services billing — hourly rates, fixed fees, and success-based fees negotiated on a per-matter basis — with no public pricing schedule. The firm is privately held by its licensed attorney principals, has no parent company, no outside equity backing, and no disclosed funding rounds or M&A activity. Recent strategic posture includes the election of two new Principals (Bin Wang, Ph.D. and Keith Wood), buildout of a Digital IP practice around AI, blockchain, open source, and NIL rights, an OpenChain/Linux Foundation partnership, and repeat top-tier recognition in IAM Patent 1000, World Trademark Review 1000, LMG Life Sciences, Best Lawyers in America, and Massachusetts Super Lawyers.
