If European or German companies want to be represented on the American market with a new product, there are two challenges to be mastered: their own invention should be protected by the most powerful US patents possible and it should be avoided to infringe other or similar patents .
It is important to know that patents are permitted in America that would not be possible in Europe and Germany. This includes applications whose subject has already been published by the inventor himself, as well as those whose subject is only partially patentable in Europe or Germany due to legal regulations as described on https://midhudsonnews.com/2020/05/10/how-does-inventhelp-support-new-inventors/.
The latter include, for example, computer-implemented processes, specific business methods such as process flows in companies or surgical, therapeutic or diagnostic processes. It is important that when writing the patent in Europe, a possible use in America is considered and prepared accordingly.
Knowledge of the so-called grace period is also important. While patenting is no longer possible in Europe if a product or application has already been presented publicly before the application, this is handled differently in the USA as you can read from https://vocal.media/journal/innovating-as-a-small-business article. In the US, an inventor or a company can present a novelty and then has twelve months to file a patent application and bring the product to patent maturity.
