Patents have a time span before it must be renewed and I beleive that the renewal can only happen once. A Patent Pending is actually better in many cases as a patent pending is very vauge to the public while a patent is definitive thus made public. Patent pending however do have an experation date if not updated. Good companies with something unique will ride the patent pending for as long as possible as it keeps the compeition at bay.
A trademark I beleive can be rewnewed indefinetly.
