Patent Prosecution
Most patents are never tested. The ones that matter always are — in licensing negotiations, in an inter partes review, in front of a jury. We draft every application as though that day is coming, because for our clients' most valuable assets it usually does.
Prosecution is the center of this firm. Since the USPTO began indexing attorneys of record in late 2015, more than ten thousand US patents have issued with Amin, Turocy & Watson named on them — and that number understates the work, because clients frequently substitute their own counsel of record before a patent issues, which removes the firm from the printed document. In 2025 the firm prosecuted 889 US utility patents to grant, which placed it 77th among all US patent firms in Harrity Patent Analytics' annual ranking. Those numbers describe a practice built for volume without being built for volume's usual compromises.
The way that works is unglamorous. Applications are drafted by people with the underlying technical training — the roster carries degrees in electrical engineering, physics, systems engineering, biomedical engineering, and molecular and micro biology — so the specification is written rather than translated. Claim sets are constructed with two readers in mind who are not the examiner: the competitor who will try to design around them, and the petitioner who will later try to invalidate them.
We represent Fortune 500 companies alongside mid-size businesses, start-ups, and individual inventors before the United States Patent and Trademark Office, and we procure and manage rights across foreign jurisdictions. For clients with substantial portfolios we handle the full lifecycle — landscape and ideation work at the front end, third-party conflict management through the middle, and continuation strategy that keeps a family responsive as the product actually changes.
An application has to satisfy an examiner. A valuable one has to satisfy a district judge construing it eight years later on a record nobody anticipated. Those are different documents, and the difference is mostly made at drafting time — in how much of the disclosure is written down, in whether the specification supports the continuation you have not filed yet, and in whether the claim terms mean something a court can hold onto.
We draft for both, which in practice means fuller specifications than the page count strictly requires and claim sets deliberately staged in scope. It costs more at the front end. It is the difference between a portfolio that can be asserted and a portfolio that can only be counted.
Clients with large portfolios do not have a filing problem, they have a coverage problem: which parts of a product are protected, which are not, and where the next three years of engineering will go. We run ideation sessions with inventors, map what issues against what ships, and use continuation practice to keep claims aimed at the market as it moves rather than as it looked at the priority date.
The same discipline governs pruning. Not every family deserves its maintenance fees, and a portfolio review that never recommends abandoning anything is not a review.
The attorneys who prosecute here also defend patents at the Patent Trial and Appeal Board and litigate them in district court. That loop is the point. A prosecutor who has watched their own claim construed under Phillips, or seen a file-history statement quoted back at them in a final written decision, drafts differently afterwards — and cannot unlearn it.
