About intellectual property
Intellectual property law protects the inventions, brands, and creative work that make modern businesses valuable. An IP attorney secures legal rights through registration, defends those rights against infringement, and structures licensing deals that turn intellectual property into revenue.
The four main IP types
- Patents — protect inventions for 20 years; require detailed application to the USPTO
- Trademarks — protect brand names, logos, and slogans that identify the source of goods or services
- Copyrights — protect original creative works (books, music, software, art) automatically; registration improves enforcement
- Trade secrets — protect confidential business information (recipes, customer lists, source code) as long as secrecy is maintained
Common IP services
- Patent prosecution: drafting and shepherding patent applications through USPTO examination
- Patent litigation: enforcing patents or defending against infringement claims
- Trademark clearance, registration, and oppositions
- Copyright registration and DMCA takedown
- Licensing agreements (royalty, exclusive, sublicensable)
- IP due diligence in M&A transactions
- Trade-secret protection plans and litigation under the Defend Trade Secrets Act
