You've got a brand, an invention, or a piece of creative work worth protecting, and a generic law firm search doesn't tell you who actually handles that kind of case. These intellectual property lawyers in New York have built a combined 456 reviews, and none of the five sits below a 4.9, with the top name backed by 120. This isn't legal advice; confirm scope and fit with a firm directly.

Short answer: Law Office of Jason H. Rosenblum, PLLC leads this list at a perfect 5.0 across 120 reviews, focused specifically on trademark registration and protection. Grant Attorneys at Law, a Chambers-recognized firm, covers patents, trademarks and IP litigation under one roof, and BOAG LAW posts a perfect 5.0 across every review on file for its patent work.

How we ranked these firms

Rating is each firm’s live Google average. Review volume is how many clients actually left a rating, ranked against the others compared. Confidence blends rating with volume, so a 4.9 built on 20 reviews scores lower than a 4.9 built on 200. Recency checks how recently people are still reviewing. No firm can pay to change these numbers; the only thing money buys on this site is the Featured badge, and none of these five paid for it.

What does trademark or patent protection cost in New York? (2026)

Federal trademark registration through the USPTO carries a government filing fee separate from attorney fees, and the total depends on how many trademark classes you’re filing under and whether your application faces an office action. Patent applications generally cost more than trademark filings given the technical drafting involved. Ask any firm for a flat-fee quote on a straightforward filing before agreeing to hourly billing.

Serving the boroughs

These firms are concentrated in Brooklyn and Manhattan’s Financial District and Midtown, and IP filings rarely require an in-person visit since most of the work is document-based. If you’re searching for an intellectual property lawyer near me in New York, the more useful filter is whether the matter is trademark, patent, or copyright, since not every firm handles all three.

What to ask before you hire an IP lawyer

  • Do you personally handle trademark, copyright, or patent matters, or is that referred out?
  • Is my filing a flat fee, or hourly, and what does the flat fee include?
  • Have you handled a filing in my specific industry before?
  • What happens if the USPTO issues an office action or rejects the initial filing?
  • How long does a typical trademark or patent filing take start to finish?
  • Do you offer a free initial consultation, and is it with the attorney directly?

Frequently asked questions

Are these rankings paid?

No. Rankings come from public Google data, ratings, review counts, and how recently people are still reviewing each firm. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another firm’s score or position.

Are all five of these genuine IP specialists?

Yes. Every firm on this page has trademark, patent, or IP litigation work as a named, confirmed practice area, backed by both Google’s categorization and the firm’s own site content.

How did you choose these five?

We searched for intellectual property lawyers in New York with a real, active Google Business Profile and ranked by rating, review volume, and recency.

What’s the difference between a trademark and a patent?

A trademark protects a brand name, logo, or slogan. A patent protects an invention. Copyright protects creative work like writing, music, or art. Confirm which one your situation actually needs before you call a lawyer, since not every IP attorney handles all three.

How often is this updated?

We last verified ratings and review counts in July 2026.

The bottom line

For a trademark filing, Jason Rosenblum, Cohn Legal, and JPG Legal are all strong, specific matches. For a patent, or a matter that spans patents, trademarks, and litigation together, Grant Attorneys at Law and BOAG LAW are the two built for that scope.
