Claim Rejections - 35 USC § 101
35 U.S.C. 101 reads as follows:
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
Claim 17 is rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter.
In claims 8, applicant has claimed “computer-readable storage medium” When applying the broadest reasonable interpretation of the claims they covers a software operation system per.
Therefore, claim 17 is directed to non-statutory subject matter as computer program, per se.
Examiner Notice
The claims 1-17 have the limitation “and/or at least one coding mode” and “and/or different code unit lengths” and “and/or a same code unit length” and “and/or at least one first coding mode”, please clarify the language features from the limitations of the claims.
Conclusion
The prior art made of record and not relied upon is considered pertinent
