Patent — Dblat in Applying fou. — Where an inventor kecps his �invention a secret, mere delay in applying for a patent will not for- feit his right thereto, or bar his subsequent application ; and delay of less than two years will not conatitute a defence against a patent in any case. �7.

If, in the eye of an ordinary observer, giving such attention as a purchaser usually gives, two designs are substantially the same ; if the resemblanoe is such as to deceive such an observer, and sufiScient to induce him to purchase one, supposing it to be the other, — the one flrst patented is infringed by the other.
