For a start
charge LESS on approval.
Charge x10 as much if rejected.
At present the financial incentive is on USPTO to approve (they get paid much more) and on big Corporations to spend more on frivolous applications than actual R&D.
Also Design Patents (Registered Design in UK) and Registered Trade names ought to be distinctive and made up.
(Fluted Coke bottle good, Apple phone bad. Kleenex good, Specsavers OK. Travelodge OK, Travel Lodge not, using ordinary words bad. Using regular names such as Ford or Dyson etc should end.)
