How does the accessibility of foreign patents affect their use as prior art?
The accessibility of foreign patents is crucial in determining their use as prior art. Even if a foreign patent is difficult to access, it may still be considered prior art if it’s publicly available. The MPEP 2126 cites the case of In re Carlson, which states:
“We recognize that Geschmacksmuster on display for public view in remote cities in a far-away land may create a burden of discovery for one without the time, desire, or resources to journey there in person or by agent to observe that which was registered under German law. Such a burden, however, is by law imposed upon the hypothetical person of ordinary skill in the art who is charged with knowledge of all contents of the relevant prior art.”
This means that even if a foreign patent is difficult to access due to geographical or linguistic barriers, it can still be considered prior art if it’s technically available to the public.
