after stating the case as above reported, delivered the opinion of the court.
We are of opinion that this decree must be affirmed. It is provided by § 4894 of the Bevised Statutes as follows: “ Sec.
*439
4894. All applications for patents shall be completed and prepared for examination within two years after the filing of the application, and in default thereof, or upon failure of the applicant to prosecute the same within two years after any action therein, of which notice shall have, been given to the applicant,- they shall be regarded a§ abandoned by the parties thereto, unless it be shown to the satisfaction of the Commissioner of Patents that such delay was unavoidable.” The applicant failed to prosecute his application within two years after the last action therein, of which notice was given to the applicant. The decree of the Supreme Court of the District -of Columbia was made on the 30th of January, 1880, and this bill was not filed until the 3d of May, 1883. No excuse for the laches' and delay is set up in the bill and none is shown in the proofs, nor is it alleged in the bill that the delay was unavoidable. Al-. though, as was said by this court in
Butterworth
v.
Hoe,
Deoree affirmed.
