U.S. Patent Office loosens rules for green tech

The U.S. Patent and Trademark Office is trying to cast a wider net to catch more green-technology inventions.
The patent office announced Friday that it has changed the application process to attract more green technologies into an accelerated patent-review program.
The Green Technology Pilot program was created in December to encourage more inventors to apply for patents relating to green technology. If accepted, those patent petitions will get priority screening under the one-year trial program.
