Firm Management

Donald M. Cislo (emeritus) and Charles H. Thomas (emeritus) started Cislo & Thomas LLP in 1979. Daniel M. Cislo joined the firm in 1987, and is currently the managing partner of the AV-rated intellectual property firm. An AV rating is the highest that can be achieved by the revered Martindale Hubble rating system. In addition, the Bar Register of Preeminent Lawyers lists Cislo & Thomas LLP among the top 5% of all law firms in the country. And although best known for our patent and copyright work, we have been ranked in the Top 50 Trademark Attorneys by Trademark Insider. We serve all of our clients’ needs in the intellectual property realm, including patent, copyright, trademark, domain name, trade secret, and trade dress areas. Our services feature searching, clearance, prosecution, licensing, maintaining, and enforcement of our clients’ intellectual property rights.

Daniel M. Cislo splits his time overseeing our Los Angeles, Westlake Village, Santa Barbara, Pasadena, Torrance, and San Diego offices, where the firm’s attorneys and paralegals provide the highest quality of intellectual property service using its proprietary Quality Client Care® or QCC® approach.

At Cislo & Thomas LLP, we use a series of weekly meetings where all attorneys, paralegals and staff evaluate the past week’s performance and determine how to better serve our clients, improve efficiency, and constantly enhance the quality of service we provide. The paramount question we ask each week is, “How can we provide the highest quality of service to our clients at the most reasonable cost, while pursuing the client’s objectives?”

In order to fully understand a client’s objectives and technology, we, as a firm, believe we must provide attorneys that began their careers as engineers and scientists, are admitted to the United States Patent Office, and are available to meet with clients, in person, at a convenient, nearby location. In addition, these same attorneys must have real-world experience in business and in handling intellectual property litigation matters before the U.S. Patent and Trademark Office, as well as in the Federal and State Courts.

We have offices throughout Southern California, namely Los Angeles, Westlake Village, and Santa Barbara. We have been successfully addressing our clients’ intellectual property needs and helping them continue to grow their business for forty years.
