IP protection: trademarks and patents

For US and non-US businesses · Searches · Filings · Registration · Monitoring · Enforcement

Your brand name, logo and inventions are some of the most valuable things your business owns, and some of the easiest to lose. A competitor can register a name you've been using, copy a product you designed, or list knock-offs on the marketplaces where you sell. We help you prepare, file and protect your trademarks and patents, in the United States and internationally, whether your business is based in the US or abroad.

What we cover

Trademark clearance

Searches of the USPTO register, international registers and common-law use to check a name or logo is available before you invest in it.

Trademark filing

US applications and international filings through the Madrid Protocol or directly with national offices.

Patent searches

Prior-art and patentability searches so you know whether your invention is likely to be protectable, and what to claim.

Patent filing

Provisional and non-provisional US applications, design patents and international filings under the PCT.

Examination support

Responses to office actions and examiner objections, and keeping every application moving to registration or grant.

Monitoring and enforcement

Watch services, renewal and maintenance deadlines, oppositions, cease-and-desist letters and marketplace takedowns.

Trademarks

A registered trademark gives you the exclusive right to use your brand name, logo or slogan for your goods and services, and the legal tools to stop others copying it.

Before you file

Filing in the United States

From filing to registration

International trademarks

Through the Madrid Protocol, a single international application based on your home application or registration can extend protection to more than 100 countries and regions. Where Madrid isn't the best route, or a country isn't a member, we coordinate direct national filings. We help you prioritise markets by where you sell, manufacture and expect to be copied.

Patents

A patent gives you the right to stop others making, using or selling your invention for a limited time. Getting one depends on filing at the right moment and describing the invention well.

Timing matters

What we prepare

Prosecution and grant

Patent examination often involves several rounds of objections from the examiner. We prepare responses and claim amendments, and help you decide when to narrow, argue or appeal. Many small businesses qualify for reduced USPTO fees as a small or micro entity, and we check your eligibility.

US and non-US clients

US businesses

File at the USPTO, then expand abroad through Madrid and the PCT before priority deadlines pass. Inventions made in the US need a foreign filing license before being filed abroad; we make sure it's in place.

Non-US businesses

Entering the US market? Non-US trademark applicants must be represented at the USPTO by a US-licensed attorney, and we handle that for you. We can also claim your home-country priority date and coordinate filings in other markets.

Some countries require inventions made there to be filed locally first, or cleared by a security review before filing abroad. We check these rules for every country involved before anything is filed.

Protecting what you've registered

Watch out for scam notices. After you file, your details become public and you may receive official-looking letters and emails demanding fees for "registration", "monitoring" or "publication". The USPTO doesn't send invoices like these. Send us anything you're unsure about before paying.

How it works

  1. Consultation. Tell us about your brand or invention, where you sell and where you plan to grow.
  2. Search and strategy. We run searches and recommend what to protect, where, and in what order, with a clear quote.
  3. Preparation and filing. We prepare the applications, you review and approve them, and we file.
  4. Examination. We respond to office actions and keep you informed in plain language at every stage.
  5. Registration and protection. Once registered or granted, we monitor for infringement and manage every renewal and maintenance deadline.
