Frequently asked questions

What does a patent law firm in Boston help with?

Services can include first-time patent applications, invention planning, existing patent matters, complex portfolios, and technology disputes. Some firms also handle trademark registration, licensing, or IP sales.

The best match depends on whether you are protecting a new product, managing an existing right, or handling a business transaction.

Can a patent attorney help with a prototype?

Yes, some firms specifically work with first-time applicants who have a prototype or are developing a new product. Before sharing technical details, ask how the consultation is structured, what information to bring, and how confidentiality is handled.

Do patent law firms also handle trademarks?

Several options cover trademark registration for products or businesses, along with broader brand-protection guidance. Ask whether the firm handles clearance, filing, responses, or ongoing trademark matters, because the scope of support can differ between offices.

What should I ask before hiring patent counsel?

Ask about experience with your technology, the exact service included, who will handle the matter, and how communication works. Request a clear explanation of the first stage and the information needed.

You should also confirm the engagement terms and how future work would be handled before committing.

Which firm is best for a complex patent portfolio?

A firm with experience coordinating complex patent portfolios and technology disputes may be a better fit than one focused mainly on first-time applicants. Discuss the number and type of assets involved, the relevant technologies, and whether coordinated support is available.
