JP21 you do realize the university owns the computers they decided to force the logo of the screensaver right? The logo on the shirts is a separate discussion. But the screensaver?
Regarding copyright and trademark law, "Trademark infringement claims generally are based on one of three legal theories. The first is a “likelihood of confusion” concept – the idea that the infringer, through the use of the senior holder’s marks, creates among consumers confusion over the origin of the goods or services in question.
A second trademark infringement legal theory is a “dilution” concept – the idea that if the senior mark holder fails over time to take action to protect its intellectual property, the marks might become so commonplace as to be considered generic and therefore no longer protectable. Dilution is also premised on the idea that if widespread infringement of famous marks occurs, then the brand value of the famous marks will be diminished in value. Applying the criteria used by courts to evaluate dilution, it appears more likely that a university might succeed against a high school with a dilution argument than with a likelihood-of-confusion claim, although once again, no college has ever attempted to litigate a trademark dilution case against a school.
The third common trademark infringement legal theory is a “tarnishment” concept – the idea that the use of marks by an alleged infringer on inappropriate products or the involvement of the alleged infringer in a scandal of some sort might damage the value of the marks to the senior holder. For instance, if a high school athletics program using the nickname, logo and mascot of a university were to be involved in an incident of hazing, sexual harassment or other misconduct resulting in extensive media coverage, the university might be damaged by association. Again, however, no college has ever attempted to litigate a trademark tarnishment case against a school.
I ultimately realize for copyright infringement of the penguin mascot image, the university or copyright holder should be contacted to request permission for its use. Maybe I'm looking at it wrong, but one would think it shouldn't be an issue for a college affiliated student group. Idk.
