Boutique U.S. patent prosecution for inventions that live in software and silicon — machine learning, computer architecture, and robotic systems — with particular depth in §101 eligibility, where these applications are most often lost.
Patent prosecution only, in technologies I actually understand — so corporate IP departments and referring firms get senior, cost-predictable work without the overhead of a large firm.
Applications drafted so the claims recite an improvement to the model — architecture, training procedure, loss function, quantization, memory and compute behavior — rather than the application of a general-purpose one. That distinction is what the Federal Circuit has left open, and it has to be in the claims.
Office action responses, examiner interviews, and appeal posture for subject-matter eligibility rejections. Grounded in what the current data shows actually moves these cases — not in what the guidance says should.
Processor and memory design, embedded and real-time systems, sensing and perception pipelines, control and autonomy. Technical subject matter handled directly by the attorney, without a translation layer.
U.S. applications claiming priority to first filings made abroad, plus docket management, IDS practice, and day-to-day prosecution counseling for companies filing first through foreign patent offices.
Klein Patent Law is the practice of William J. Klein, a registered U.S. patent attorney with a Computer Engineering background and decades of in-house intellectual property experience at a global automotive-technology company — work that moved steadily from mechanical and electronic systems into software, sensing, perception and machine learning.
That path is the reason this practice sits where it does. The hardest prosecution problems in automotive technology became the same problems facing anyone patenting a model: eligibility, claim scope that survives, and an examiner who needs to be shown the technical improvement rather than told about it.
The firm is built to be the reliable outside partner for that work — responsive, deadline-driven, and cost-conscious, with the named attorney handling the matter personally rather than handing it down.
Partner-level attention — the attorney you hire is the attorney who does the work.
Flat, predictable pricing on core prosecution tasks, built to save against conventional outside-counsel rates.
Docket-first discipline — priority and office-action deadlines tracked and met, every time.
Referrals from other firms and conflicts-driven overflow are welcome.
