The database may ignore punctuation characters (e.g., apostrophes and hyphens) or treat them as spaces. Accordingly, names with spaces, apostrophes, and hyphens may require a variety of searches in order to locate the specific name you are seeking. Examples of the names that may require more than one type of search include:
For example, to search for "McKenna" it may be desirable to enter "(Mc and Kenna) or McKenna".
A practitioner's first name may also be entered to reduce the total number of names produced in the search results.
The PTO is in the process of developing improved search capability.
