Intellectual Property Attorneys

106,079 verified ip attorneys across the United States. IP attorneys protect inventions, brands, and creative work through patent prosecution, trademark registration, copyright, and trade-secret enforcement.

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

When to talk to an IP attorney

  • You have invented something potentially patentable
  • You are choosing a brand or product name and need clearance
  • You discovered infringement of your patent, trademark, or copyright
  • You received a cease-and-desist letter
  • You are licensing IP in or out
  • You are about to launch a business and want to lock down IP before competitors do

Frequently Asked Questions about IP

How much does it cost to file a patent?
A utility patent application typically costs $8,000 to $15,000 in attorney fees through the first office action, plus USPTO fees that scale by entity size. Provisional patent applications can be filed for $2,000 to $5,000 to lock in priority while you decide whether to pursue full prosecution.
How long does a patent take?
USPTO prosecution typically takes 2 to 4 years from filing to issuance. Accelerated programs (Track One, age-based, COVID-related) can produce decisions in under a year for an additional fee.
Do I really need to register my trademark?
You acquire some common-law trademark rights through use, but federal registration gives you nationwide priority, the right to use the ® symbol, statutory damages in counterfeiting cases, and customs enforcement against imports. For any brand worth defending, federal registration is the standard.
Is software patentable?
Yes, but the bar is high after recent Supreme Court decisions. Software patents must claim a specific technical improvement, not just an abstract idea implemented on a generic computer. An experienced patent attorney drafts claims that survive 101 challenges.
What is a copyright vs a trademark?
Copyright protects original creative works (the lyrics and recording of a song). Trademark protects brand identifiers (the band name on the album cover). The two often coexist in the same product and require coordinated protection.
I received a cease-and-desist letter. What do I do?
Do not ignore it and do not respond off-the-cuff. Have an IP attorney evaluate the claim, your defenses, and the cost/benefit of fighting, redesigning, or licensing. Many demands are weaker than they look; others are existential. Early analysis saves money.
