At the request of the comic strip copyright holders, Lockheed changed the name of the advanced development company to "Skunk Works" in the 1960s. The name "Skunk Works" and the skunk design are now registered trademarks of the Lockheed Martin Corporation. The company also holds several registrations of it with the United States Patent and Trademark Office. They have filed several challenges against registrants of domain names containing variations on the term under anti-cybersquatting policies, and have lost a case under the .uk domain name dispute resolution service against a company selling cannabis seeds and paraphernalia, which used the word "skunkworks" in its domain name (referring to "Skunk", a variety of the cannabis plant). Lockheed Martin claimed the company registered the domain in order to disrupt its business and that consumer confusion might result. The respondent company argued that Lockheed "used its size, resources and financial position to employ 'bullyboy' tactics against... a very small company."
