As of 2004, Monster owned about 300 trademarks,
[13] 70 of which are related to the word "Monster".
[14] By 2009, the company had made 190 filings with the
U.S. Patent and Trademark Office.
[14] Most filings were to delay potentially infringing trademark applications so Monster could study them. Some were formal oppositions
[13] and about 30 have resulted in lawsuits.
[14][15][16] Most lawsuits were settled with non-disclosed terms.
[14] Critics and defendants say that Monster is too aggressive in pursuing trademark protections against companies that do not have confusingly similar products and that it is trying to own a common word, not protect a brand. Monster representatives say they are doing what most "premium" brands do to protect their marks and that their products include things like clothes, mints and music.

In the 2000s, Monster had legal disputes over its trademarks with
Monster.com, and the
Discovery Channel for its show

[13] Monster also had trademark disputes with
Bally Gaming International over its slot machines, Monster Slots, with Hansen Beverage Co. for its
Monster Energy drink, and the Chicago Bears, who use the nickname "Monsters of the Midway."
[15] Other trademark disputes include a 2001
[17] lawsuit against
The Walt Disney Company for products related to the film
Monsters, Inc.,
[14] and a claim against an online used clothing retailer, MonsterVintage LLC.
[14] In 2004, Monster filed a complaint about the trademark application from Snow Monsters, a video website with skiing content for kids. The Snow Monsters owner initiated a lawsuit against Monster pre-emptively.
[13] It has also had a trademark dispute with the job site, Monster.com.

In 2006 Monster brought a suit against Monster Mini Golf, a company selling franchise Mini Golf locations throughout the US. After an unsuccessful legal mediation, Monster Mini Golf launched a grassroots campaign against Monster Cable on the Internet. As a result, Monster received more than 200 complaints from the public. Monster Cable dropped the lawsuit and agreed to pay up to $200,000 of Monster Mini Golf's legal fees.
[14] In 2009 Monster Cable CEO Noel Lee said on Fox Business that the company has had to balance their trademark protection efforts with the public's point-of-view.
