The USPTO has proposed fee increases in addition to the already implemented 15% surcharge.

Concerning Design Patents, the proposal sets several modest fee increases, while others are quite substantial.  Namely, the proposed Design Patent Examination and Search Fees would each increase by several hundred dollars.  The following table compares current and proposed large entity fees.  The proposed small and micro entities fees are, respectively, 50% and 25% of the large entity fees.

Fee Item	Current	Proposed	Percent Change
Filing Fee	$ 250	$ 260	4 %
Examination Fee	$ 160	$ 500	213 %
Search Fee	$ 120	$ 420	250 %
Issue Fee	$ 990	$ 1,020	3 %

Extension Fees	Current	Proposed	Percent Change
First Month	$ 150	$ 200	33 %
Second Month	$ 560	$ 600	7 %
Third Month	$ 1,270	$ 1,400	10 %

Obviously, the proposed fee increases will cause a substantial increase in Design Patent filing costs.  The current Filing, Examination and Search fees total $ 530, whereas the proposed fees total $ 1,180, more than twice the current fees.
