Regal Crown Club Credit Claim Code

21.1 Code/claim comparison skills

21.2 Code/claim comparison process

  • 21.2.0 Applicable to both infringement & invalidity charts, and to practicing/working charts
  • 21.2.1 Provisionally parse the claim into “limitations”
  • 21.2.2 Provisionally interpret each element of the claim (Provisional claim construction)
  • 21.2.3 Locate each limitation in the code
  • 21.2.4 Provisionally map code & limitation
  • 21.2.5 Verify code/claim mappings consistency
  • 21.2.6 Verify that all elements/steps are present (P showing infringement is AND; while D showing non-infringement is OR [show absence of any one element], D showing anticipatory prior art is AND: “all-elements rule”)
  • 21.2.7 Verify that components form a whole (no “bag of parts”, “laundry list”) [turning claim into “parts list” is important, but insufficient]
  • 21.2.8 Verify any specific connectives (the importance of small words)
  • 21.2.9 Verify that elements/steps “face in same direction” as claim [e.g. server- vs. client-based]
  • 21.2.10 Consider equivalence or obviousness

21.4 Obviousness [combining multiple source-code references, and combining source-code with non-source references; actually, all charts will likely combine source with non-source references]
