Leo Stoller had made a name for himself in trademark circles as a self-proclaimed "intellectual property entrepreneur." Stoller, through his companies Rentamark.com, Stealth Industries Inc., S Industries, Inc., Sentra Sporting Goods U.S.A., and Central Mfg. Co. or in his own name, has claimed rights to an extensive catalog of allegedly famous trademarks and vigorously asserted those rights against people and companies that adopted similar or identical marks. Stoller's claimed inventory of marks included STEALTH, SENTRA, DARK STAR, AIR FRAME, TRIANA, STRADAVERIUS, HAVOC, CHESTNUT, TRILLIUM, FIRE POWER, LOVE YOUR BODY, and many others.
Stoller's modus operandi usually included sending a cease-and-desist letter, threatening infringement actions against those who did not license their use of the subject trademark. The cease-and-desist letter often appeared to be printed on generic letterhead with the trademark in which Stoller claimed rights inserted as appropriate. In later versions of his standard cease-and-desist letter, Stoller would brazenly write that settlement negotiations and pre-filing discovery or exchange of information was a fruitless exercise. In his eyes, license and litigation were the only choices. Stoller was able to maintain this business model because license fees are often far less than the cost of defending against the potential litigation.
Throughout his "intellectual property entrepreneur" career, Stoller managed to ruffle the feathers of not only the alleged trademark infringers he pursued, but the courts and administrative bodies before which he prosecuted his claim when he failed to secure a license. The weak link of Stoller's business model was that frequently, he had no interest or protectible rights in the trademarks he asserted against others, rendering his claims entirely baseless, vexatious and wasteful of time and money. Most if not all of his trademark registrations were supported by documents alleging use of these marks that were at best suspect and Stoller often prolonged litigation in bad faith to the ire of the litigants and courts. These activities got Stoller into much hot water. In recent years, the Trademark Trial & Appeal Board at the U.S. Trademark Office has vacated Stoller's pending requests for extensions of time to oppose published trademarks and prohibited Stoller from filing any additional extensions for a period of two (2) years extending until July 2008. Once this suspension is lifted, Stoller can only file extension through an attorney. The federal court for the Northern District of Illinois went a step further and precluded him from filing any further lawsuits without first obtaining leave from the Court.
So what is next for Leo? This past August, the bankruptcy court in the Northern District of Illinois approved the sale of Stoller's trademark assets, whatever they may be, to the Society for the Prevention of Trademark Abuse, LLC, an entity set up for the sole purpose of acquiring Stoller's assets and rescinding or modifying any license agreements based on unfounded claims. Stoller continues to fight, filing appeals where ever he can and posting notices on his blog to potential purchasers or licensors of marks from the SPTA, that title to these assets may be sufficiently clouded. So the battle rages on...
