`Reply to Office Action Dated August 31, 2020
`
`REMARKS
`
`Applicant respectfully requests reconsideration of this application in view of the above
`
`amendments and the following remarks. Claims 7-8, 10-14, and 16-18 will be pending upon entry
`
`of this amendment. Claims 7, 10-13, and 16-18 are amended. Claims 1-6, 9, 15 and 19-20 have
`
`been canceled. No new matter has been addedto the application.

`
`As a preliminary matter, applicant notes that Narroschkeet al. (US 20130101027) cited
`
`in the office action was notlisted in Form PTO-892. For completeness, applicant submits
`
`herewith a supplemental IDS to place Narroschkeet al. (US 20130101027) officially on record.
`
`Rejections Under 35 U.S.C. § 103 are Overcome.
`
`Claims 1-5, 7-11, 13-17, and 19-20 are rejected under 35 U.S.C. 103 as being
`
`unpatentable over Norkin et al. (“Norkin”) (US 20130294525) in view of Norkin et al. (“Norkin
`
`‘814”) (US 20130329814).
`
`Claims 6, 12, and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Norkin
`
`and Norkin ‘814, in view of Narroschkeet al. (“Narroschke”) (US 20130101027).
`
`Applicant has amendedindependentclaims 7 and 13, as set forth above, to more
`
`particularly recite the subject matter that applicant considers as their invention. Support for the
`
`amendmentis found, for example, in 9{][0342]&[0343] of the application as published (US
`
`2020/0036975), reproduced below:
`
`Next, a fourth approach for changing weights asymmetricallyis
`FO342]
`described. Loop filter £20 performs a filter calculation using a filter
`coefficient of a reference filter. Next,when a change amount Ain pixel value
`before and after the Alter calculation exceeds a clip width which is a reference
`value, loop filter 120 clips the change amount Ato the chp width. Loop filter
`120 sets asymmetrical clip widths across a block boundary.
`
`Specifically, loop filter 120 makes a clip width for a pixel having
`[0343]
`alarge error widerthan the clrp width of a pixel having a small error. For
`example, loop filter 120 makes the clip width for the pixel having the large
`error to a constant multiple of the chip width for the pixel having the smaller
`etror, As aresult of changing the clip width, the value of the pixel having the

`
`In addition, the value of
`small error is prohibited from changing significantly.
`the pixel having the large error is allowed to change significantly.
`
`Amendedclaims 7 and 13 now recite “changing values of pixels in the first block and the
`
`second block by using the first filter and the second filter such that change amounts of the
`
`respective values are within respective clip widths, the pixels in the first block and the second
`
`block being arranged alongaline across the boundary, and the clip widths are asymmetric with
`
`respect to the boundary.” Performing the filtering using the asymmetrical filter characteristic
`
`across the block boundary makesit possible “that the error can be reduced.” Appl., 40120].
`
`In contrast, Norkin ‘814, referring to its FIG. 1, relates to determining the numberofpixels
`
`to be filtered based on decision values calculated respectively for the right and left of the border
`
`or boundary.
`
`In particular, J9[0064]-[0069] of Norkin ‘814, reproduced below, describes that
`
`threshold value “thr1” is used for a current block, and threshold value “thr2” is used for a
`
`neighboring block. Significantly, these threshold values are compared with the decision values. In
`
`other words, the threshold values in Norkin ‘814 are not threshold values related to clipping in
`
`computation performed onthe pixels to be filtered.

`
`Norkin ‘814, in [0012], describes that clipping is performed on an offset (A) amountin
`
`a pixel value, in the following equation, reproduced below:

`
`The equation, however, merely illustrates that
`
`tc, which depends on quantization
`
`parameter (QP), is used for a clip width. Thus, Norkin ‘814 fails to disclose or suggest “changing
`
`7

`Reply to Office Action Dated August 31, 2020
`
`values of pixels in the first block and the second block by usingthefirst filter and the secondfilter
`
`such that change amounts of the respective values are within respective clip widths, the pixels in
`
`the first block and the second block being arranged along a line across the boundary, and the clip
`
`widths are asymmetric with respect to the boundary” as now moreparticularly recited in claims 7
`
`and 13.
`
`The rest of the prior art does not cure the deficiencies of Norkin ‘814.
`
`Thus, the priorart, alone or in any combination, fails to teach or suggest the subject matter
`
`now moreparticularly recited in claims 7 and 13, as amended.
`
`Based on the foregoing, applicant respectfully submits that claims 7 and 13 as amended
`
`are now clearly allowable. Allowance of claims 7 and 13, as well as their respective dependent
`
`claims, is respectfully requested.

`
`Conclusion
`
`Forat least these reasons, Applicant respectfully requests allowance of the pending claims.
`
`In the event the Examinerfinds minor informalities that can be resolved by telephone conference
`
`or if the Examinerbelieves a telephone conference would facilitate prosecution of this application,
`
`the Examiner is urged to contact Applicant’s undersigned representative by telephone at (206)
