`Appeal 2023-000855
`Application 17/048,380
`
`BACKGROUND
`
`The subject matter on appeal relates to biodegradable layered
`
`composites said to be useful, e.g., for controlling weed growth and moisture
`
`in agricultural applications. E.g., Spec. {{ 1, 2; Claim 1. Claim 1 is
`
`reproduced below from page 6 (Claims Appendix) of the Appeal Brief
`
`(emphasis addedto key disputed limitation) (formatting added):
`
`1. A biodegradable layered composite comprising:
`
`a first nonwoven biodegradable layer having a first and second
`major
`surface,
`the
`first nonwoven biodegradable
`layer
`comprising:
`
`biodegradable polymeric melt-blownfibers, and
`
`a plurality ofparticles enmeshedin the biodegradable polymeric
`melt-blown fibers; and
`
`a biodegradable polymer film on at least a portion of the first
`major surface of the first nonwoven biodegradable layer.

`
`Appeal 2023-000855
`Application 17/048,380
`
`ANALYSIS
`
`The Appellant argues the claims as a group. Weselect claim | as
`
`representative, and the remaining claimswill stand or fall with claim 1.
`
`After review of the cited evidence in the appeal record and the
`
`opposing positions of the Appellant and the Examiner, we determine that the
`
`Appellant has not identified reversible error in the Examiner’s rejections.
`
`Accordingly, we affirm the rejections for reasonsset forth below,in the
`
`Final Action dated April 1, 2022, and in the Examiner’s Answer dated
`
`August 19, 2022.
`
`There does not appear to be any dispute that, in Wong, filler particles
`
`such as calcium carbonate are integrated into polymeric melt-blownfibers;
`
`1.e., the particles are embedded in and onthe surfaces of the fibers, not
`
`merely surroundedby,held in place, and/or entangled by the fibers. See
`
`generally Final Act.; Appeal Br.; Ans. The sole issue on appeal is whether
`
`particles that are embedded in andon the surfaces of the fibers, and
`
`surroundedby the other fibers of the fabric, fall within the broadest
`
`reasonable construction, consistent with the Specification, of the claim |
`
`limitation, “particles enmeshed in the biodegradable polymeric melt-blown
`
`fibers.”
`
`Wedeterminethat they do, and therefore we affirm the Examiner’s
`
`rejection. As the Examiner explains, Ans. 3-4, the Specification defines the
`
`term “enmeshed” as encompassing “particles that are dispersed and
`
`physically held in the fibers of a nonwoven biodegradable layer.” Spec. | 6
`
`(emphasis added). The Specification states that “[t]he particles become
`
`enmeshed in a melt-blow fibrous matrix as the fibers contact the particles.”
`
`Spec. | 17. The definition in { 6 does not define “enmeshed”as requiring
`
`
`
`Appeal 2023-000855
`Application 17/048,380
`
`the particles to merely be surrounded by or entangled by the fibers but not
`
`embeddedin the fibers; on the contrary, it defines the term “enmeshed”as
`
`encompassingparticles that are “held in the fibers,” which is consistent with
`
`{| 17’s reference to the particles “contact[ing]” the melt-blown fibrous
`
`matrix. See id.
`
`There is no dispute that the particles in Wong are held in the fibers,
`
`and that those particles in turn are surrounded by and entangled with other
`
`fibers in the fabric. Given the disclosures in the Specification noted above,
`
`which the Appellant does not acknowledgeor address, the Appellant fails to
`
`identify reversible error in the Examiner’s determination that Wong’s
`
`particles fall within the broadest reasonable construction, consistent with the
`
`Specification, of the disputed term. See In re ICON Health & Fitness, Inc.,
`
`496 F.3d 1374, 1379 (Fed. Cir. 2007) (“[T]he PTO must give claimstheir
`
`broadest reasonable construction consistent with the specification.”); cf. In
`
`re Zletz, 893 F.2d 319, 321 (Fed. Cir. 1989) (“[D]uring patent prosecution
`
`when claims can be amended, ambiguities should be recognized, scope and
`
`breadth of language explored, and clarification imposed.”).
`
`Weaffirm the Examiner’s rejection.
