Practice area guide
What does a patent lawyer do?
Patent law covers inventions: patentability and freedom-to-operate searches, drafting and prosecuting patent applications, oppositions and post-grant challenges, licensing and technology transfer, and infringement litigation. Patents are granted country by country or through regional offices, and in many countries patent attorneys are a separate regulated profession.
How do I choose a patent lawyer?
- Check for a technical background in your field, such as chemistry, software or engineering.
- Ask which patent offices the lawyer or attorney files at directly and where local agents are used.
- Keep the invention confidential and bring drafts, lab notes and any earlier disclosures or filings.
Where can I find a patent lawyer near me?
