“White Space” is the area with little or no patenting activity

Standard Methods for Finding White Space
A)
1. Search for and study all that has been done.
2. Use imagination to extrapolate to what has not been done (new ideas).
Or
B)
1. Get an idea.
2. Look in the literature to see if it’s been done.

Proposed New Method for Find White Space:
• 1. Search for all that has been done.• 2. Compare against a defined “universe”
to find what has not been done.

Analysis of Structure White Space
• The same process can be used on either the manual codes or fragment codes to find structure white space
• For purposes of white space analysis, the BCE fragment code system is more appropriate since it is more thorough

Notes About Usage
• A thorough search is necessary to define the starting data set
• The white space analysis is only an idea generation tool
• Once new ideas are generated, thorough searches are again needed.

Conclusions
• Derwent’s Manual and Fragment Code systems may be used to define a “universe” for white space analysis
• The Manual Code system is better for finding use white space, while the Fragment Code system is better for structure white space.
