Comments: Assignees are shown where listed in the patent application records, otherwise the inventors are listed. If the inventor has a corporate affiliation, I've shown it. It's important to realize that some of these applications may not be approved; many others may be approved, but only after modifications (usually to restrict the scope of the patent claims.)
