What Makes Intellectual Property Cases Unique in California?

Litigation proceeds through California's Superior Court system, with appellate review available through the Court of Appeal. Local court rules and judicial temperament vary across the state. Attorneys who regularly handle intellectual property cases in California factor these state-specific rules into their strategy from the outset.

When Should You Hire a Intellectual Property Lawyer in California?

Delaying legal consultation in California intellectual property cases creates tangible risks. California imposes a 4 years written, 2 years oral deadline for filing these claims. Missing this statutory window extinguishes your right to pursue the matter, regardless of its merit. Engaging an attorney before disclosing inventions publicly, when IP infringement is discovered, or when licensing intellectual property ensures that deadlines are identified, evidence is preserved, and your legal position is protected from the earliest stage.
