In trademark applications, small differences can make all the different, as two recent decisions show.
In the first, the registration of the trade mark RESVEROL for pharmaceutical products was prevented by the owner of the existing mark LESTEROL. The difference between the trade marks is but two letters, but the patent court considered that as the application was under the same category for an essentially identical good, there was a likelihood of confusion between them.
However, when the owner of the trade mark TOLPOSAN opposed the registration of TONOPAN (three letters different), the opposition failed and the new trade mark was allowed to be registered.
