America Invents Act

This legislation contains some very significant changes to US Patent and Trade Mark Practice.  However, some of these changes will not be effective for 12-18 months. 

Important changes include:   

  • There are first inventor to file priority provisions. 
  • There are new post grant procedures. 
  • There are new inter-parties procedures. 

More specifically, the Act has immediate effect to increase Patent and Trade Mark Office fees by 15% on almost all fees including maintenance fees.
