Orange County Intellectual Property Lawyer

Callahan & Blaine, PC represents Orange County and Southern California companies in intellectual property litigation, both enforcing intellectual property rights and defending against infringement claims. Our clients range from entrepreneurs and small businesses to established companies and large corporations in disputes involving trademarks, copyrights, trade secrets, licensing agreements, advertising practices, and proprietary processes, including matters that arise online through websites, digital commerce, and domain name conflicts. The firm has tried complex civil cases since 1984, and it brings that trial capability, along with a nationally recognized strength in integrating insurance coverage into complex litigation, to intellectual property disputes. To see how this work fits within the firm’s broader courtroom practice, explore our civil litigation practice areas.

How Can an Orange County Intellectual Property Attorney Help?

Our attorneys develop and carry out litigation strategies in intellectual property disputes, and they are equally prepared to prosecute an infringement claim or to defend a company accused of infringement. That dual capability matters, because the same command of the underlying facts and the applicable law drives both sides of a dispute. Where insurance coverage may respond to a claim, the firm draws on its coverage experience to help a client fund a defense or pursue a recovery, an approach that has become a core strength across the firm’s business litigation work.

Types of Intellectual Property Litigation We Handle

Intellectual property issues can appear as a significant part of a larger transaction or lawsuit, or they can stand alone as substantial problems with long-term consequences. Our attorneys advise and represent companies of many sizes on matters that include the following.

  • Trademark, copyright, and domain name protection and infringement disputes
  • Trade secret misappropriation, confidentiality, and nondisclosure matters
  • Licensing agreement disputes, including royalty and scope of use questions
  • Unfair competition and false advertising claims
  • Disputes over fair use, image rights, and royalties
  • Intellectual property aspects of business purchases, sales, and e-commerce, including cybersquatting and domain name disputes

Trademark and Copyright Disputes

Enforcement of trademark and copyright rights against infringement and defense of companies accused of infringement, including claims over branding, logos, trade dress, and protected works in state and federal court.

Trade Secret Litigation

Litigation over the misappropriation of formulas, methods, processes, and other confidential information, often arising when a former employee or business partner takes protected information, with a focus on limiting the damage to the company.

Licensing and Unfair Competition

Disputes over the breach of licensing agreements, royalty and scope of use questions, and unfair competition and false advertising claims that affect a company's market position and revenue.

California businesses face particular exposure to trade secret theft, copyright infringement, and trademark disputes as digital commerce continues to expand. Our attorneys help Orange County companies identify vulnerabilities, respond to infringement threats, and pursue or defend litigation in both state and federal courts. The federal agency that administers trademark and patent registration, and a useful reference on the rights at issue in many of these disputes, is the United States Patent and Trademark Office.
Proven Results Since 1984

With decades of courtroom success across California, our attorneys are prepared to fight for the outcome you deserve.

Frequently Asked Questions

Does Callahan & Blaine, PC enforce intellectual property rights, defend against claims, or both?

The firm does both. Our attorneys prosecute infringement and misappropriation claims on behalf of companies whose intellectual property rights have been violated, and they defend companies accused of infringing the rights of others. Because the same command of the facts and the law drives both sides of an intellectual property dispute, handling matters from both positions strengthens the firm’s judgment on any given case.

Our attorneys handle trademark, copyright, and trade secret disputes, licensing agreement disputes, unfair competition and false advertising claims, and questions of fair use, image rights, and royalties. The firm also addresses the intellectual property issues that arise in business purchases and sales and in e-commerce, including domain name and cybersquatting disputes. These matters are litigated in both state and federal court.

Trade secret disputes frequently begin when a former employee or business partner takes confidential information such as a formula, method, process, or client data and uses it in competition with the company that developed it. These matters often overlap with employment and contract issues, and a prompt response is important because the value of a trade secret depends on keeping it confidential. Our attorneys move quickly to limit the damage while pursuing the available legal remedies.

Domain name disputes involve conflicts over website addresses, and they often involve trademark infringement when a domain uses a protected mark or cybersquatting when a domain is registered in bad faith to profit from another company’s brand. These disputes may be resolved through negotiation, through arbitration under the Uniform Domain Name Dispute Resolution Policy administered by ICANN, or through litigation. Our attorneys handle domain name disputes as part of the firm’s broader intellectual property practice.

Depending on the type of intellectual property and the nature of the infringement, available remedies may include compensatory damages for actual losses and lost profits, statutory damages for certain trademark and copyright claims, recovery of the infringer’s profits, and injunctive relief that stops further infringement. Enhanced damages and the recovery of costs and attorney fees may be available in appropriate cases. The remedies that apply to a particular matter depend on the facts and the strength of the evidence, which our attorneys assess early in the case.
