It has been reported this week that the United States Patent and Trade Mark Office has regulations limiting the size of new patent applications.
The regulations were implemented in an attempt to avoid to drastically reduce the time spent by the USPTO in examining an application. However various high profile companies took legal action against the USPTO in order to have the rules overturned. The rules were fought on the grounds that they were beyond what was necessary and that the changes were beyond the scope of the USPTO.
The changes which have now been overturned limited the number of claims that a new application could make as well as putting limits on follow up filings.
