So if I advertise my kissogram service using that word then people will think it&#x27;s from Instagram?<p>How about my hydraulics company BigRam?<p>Suppose you think Apple are infringing Facebook by using the term face-time?<p>Good TM protection is stopping people from using your trademark in a way that confuses the origin of goods&#x2F;services of theirs as being yours.<p>Littergram if surely a reference to sending a message (-gram) about litter.<p>Similarly, FWIW, Instagram aren&#x27;t ripping off Instapaper either in my opinion but they&#x27;re a lot closer to it than the Littergram service.<p>If Instagram wanted a more unique name they should have chosen one that wasn&#x27;t the combination of a well-known prefix and suffix.
