Leo D. Stoller (born June 5, 1946) is an American self-styled "intellectual property entrepreneur" based in suburban Chicago, Illinois. Stoller claimed rights to a large inventory of well-known trademarks and engaged in the assertive enforcement of those alleged trademark rights, threatening infringement action against people and companies who attempt to use similar marks.

Though he managed to obtain license payments in some circumstances through demand letters, Stoller lost some key challenges in federal court, and was sanctioned by United States regulators for filing thousands of motions. A federal court labeled Stoller and his companies as "vexatious litigants" in 2005, and his bankruptcy filing from that year was converted to a liquidation in 2006 after the judge found Stoller's filing to have been made in bad faith. On August 8, 2007, the bankruptcy court approved the sale of Stoller's trademark assets to the Society for the Prevention of Trademark Abuse, LLC.In re Leo Stoller, Debtor, no. 05-B-64075 (N.D.

Stoller has filed oppositions to others' trademark applications with the USPTO Trademark Trial and Appeal Board (TTAB) numerous times, and filed applications for extension of the deadline to file such oppositions even more times. Stoller claims a number of large and small companies have resolved trademark controversies. When approaching infringers, Stoller is reported to document his claims with copies of letters which demonstrate capitulation with his demands. Such letters are said to be from companies such as K-Mart, and often marked "Confidential".

Trademark litigation

S Industries, Inc. v. Centra 2000 In 1996 S Industries, Inc. filed suit alleging that Centra 2000, a producer of data management software, infringed its/Stoller's "Sentra" trademark in violation of the Lanham Act. District Judge George W. Lindberg ruled in favor of Centra 2000, finding that S Industries did not hold a federal registration for the "Sentra" mark for use on computer hardware or software. Because S Industries' claims were, in the judge's view, completely unfounded and because its procedural maneuvering multiplied the cost of defending against the suit, Centra 2000 was awarded attorney's fees in July 1998.S Industries, Inc. v.

Central Manufacturing Co. v. Brett

A case decided by summary judgment on September 30, 2005, Central Manufacturing Co. v. Brett,Central Mfg Co. v. Brett (No. 1:04-cv-03049 (N.D. Ill. Sept. 30, 2005)) pitted a Stoller-owned company against Hall-of-Fame baseball player George Brett, whose company, Brett Brothers Sports International Inc., sells a bat under the name "Stealth". It was alleged in this case that the use of that name infringed upon Stoller's trademark rights.

In its decision, the United States District Court for the Northern District of Illinois determined that there was no likelihood of confusion where consumers would mistakenly regard Brett's bats as being from Stoller's company. The court also found that Stoller failed to provide adequate proof that his company and its licensees had even sold baseball-related merchandise at all. The court found likelihood of confusion in the opposite direction, found Brett's trademark rights to be senior, and hence canceled Stoller's (Central Manufacturing) registration. In the decision, the court described Stoller's tactics and enumerated dozens of unsuccessful infringement cases he had brought in that court.

Chief Judge Charles P. Kocoras from the Northern District of Illinois then issued a citation to Stoller after reviewing his "filing history" having filed at least "49 lawsuits in this court, individually or through one of his many wholly owned corporations". "The Executive Committee (of the Northern District of Illinois) in its capacity as the supervisor of the assignment of cases, has directed that Leo Stoller inform this court of any claim by him why the Executive Committee should not impose reasonable and necessary restraints upon Mr. Stoller's ability to file civil cases in this District." After a thorough review of Leo Stoller's entire filing history the Executive Committee of the Northern District of Illinois issued a decision stating that "the committee will take no further action in this matter."

On July 9, 2007, in an opinion that opened with a laudatory description of the George Brett "Pine Tar Incident", the United States Court of Appeals for the Seventh Circuit affirmed the District Court's judgment, including the order for Stoller to pay Brett's attorney fees.https://caselaw.findlaw.com/us-7th-circuit/1458523.html

Target and Google trademark claims

Stoller filed an opposition with the Trademark Trial and Appeal Board (TTAB) in April 2006 to the Target Stores bullseye logo.

In 2006, Stoller filed an opposition to Google's attempt at registering a trademark to the name "Google" in the category of exercise balls. Stoller claims that the "Google" mark has become generic, yet also claims that it infringes on prior alleged rights to the name held by Stoller's company. The case against the Google mark, however, was dismissed with prejudice at the instigation of Stoller's trustee in bankruptcy, who is empowered to take action in all cases in which Stoller and his companies are involved. Subsequently, on January 19, 2007, Google filed a suit against Stoller's companies alleging violations of the anti-racketeering RICO law.http://www.roylance.com/Uploads/CentralMfgCo/Complaint%20FILED.pdf
