`
`I.
`
`Status of the Claims
`
`REMARKS
`
`In the Final Office Action, the Examiner rejected claims 15 and 16 under 35 U.S.C.
`
`§ 102(b) as being anticipated by U.S. Patent Application Publication No. 2003/0236588
`
`("JANG"); rejected claims 18-20 under 35 U.S.C. § 102(b) as being anticipated by U.S. Patent
`
`No. 5,340,433 ("CRUMP"); and allowed claims 1-14 and 17.
`
`Applicant wishes to thank the Examiner for allowing claims 1-14 and 17.
`
`By this Reply, claims 16 and 19 have been amended, without adding new subject matter.
`
`No claims have been cancelled. Accordingly, claims 1-20 remain pending in this application.
`
`II.
`
`Claim 15 Rejection (JANG)
`
`In the Final Office Action, the Examiner rejected independent claim 15 as being
`
`anticipated by JANG. See Office Action at 2.
`
`Independent claim 15 recites a method of manufacturing a three-dimensional object that
`
`comprises, among other things, "discharging from [a] nozzle a path of composite material
`
`containing [a] continuous strand material and [a] filler material at least partially coated with the
`
`curable liquid material." Because JANG does not teach or suggest all elements recited in
`
`independent claim 15, the rejection of independent claim 15 should be withdrawn.
`
`In the Final Office Action, the Examiner suggested that JANG discloses all of the
`
`elements of independent claim 15, and pointed specifically to paragraph [0072] of JANG for
`
`alleged support of this suggestion. See Final Office Action at 4. However, paragraph [0072]
`
`discloses only that reinforcement fibers and a matrix material can be mixed to form a continuous
`
`tow of impregnated fibers, which is subsequently "pulled from a fiber spool 4 ... submerged in a
`
`resin bath ... [and] driven to enter. .. nozzle 22." In other words, paragraph [0072] of JANG
`
`-7-
`
`Page 7 of 11
`
`Markforged Ex. 1020
`Markforged v. Continuous Composites, IPR2022-01218
`
`
`
`Application No. 15/267,956
`Attorney Docket No. 13087.0003-02000
`
`describes only how to make a tow, which is later discharged with only resin from the nozzle
`
`(22). Nowhere in paragraph [0072] (or elsewhere in JANG) is there any mention of a filler
`
`material being discharged together with a continuous strand material and a curable liquid
`
`material, as required by independent claim 15.
`
`III.
`
`Claim 16 Rejection (JANG)
`
`In the Final Office Action, the Examiner rejected independent claim 16 as being
`
`anticipated by JANG. See Office Action at 2.
`
`Independent claim 16, as now amended, recites a method of manufacturing a three(cid:173)
`
`dimensional object that comprises, among other things, "aiming a curing device at a path of
`
`composite material at a location outside of [a] nozzle to cure [a] curable liquid material; and
`
`moving the curing device together with the nozzle." Because JANG does not teach or suggest all
`
`elements recited in independent claim 16, the rejection of independent claim 16 should be
`
`withdrawn.
`
`In the Final Office Action, the Examiner suggested that JANG discloses all elements of
`
`independent claim 16. Specifically, the Examiner suggested that JANG discloses "aiming [a]
`
`curing device at a path of composite material as illustrated in Fig. 4[,] wherein the heating
`
`elements surround[s] the path of composite material." See Final Office Action at 4.
`
`While JANG may disclose heating elements (88), the heating elements (88) are not aimed
`
`at a path of composite material at a location outside of a nozzle. In contrast, as the Examiner
`
`pointed out, the heating elements (88) surround a path of composite material only while the
`
`material is inside of the nozzle (22).

`
`IV.
`
`Claim 18 Rejection (CRUMP)
`
`In the Final Office Action, the Examiner rejected independent claim 18 as being
`
`anticipated by CRUMP. See Office Action at 3.
`
`Independent claim 18 recites a method of manufacturing a three-dimensional object that
`
`comprises, among other things, "adjusting a trajectory of [a] path of composite material after
`
`discharge from [a] nozzle; and curing [a] curable liquid material in the path of composite
`
`material after adjusting" (emphasis added). CRUMP fails to disclose any trajectory being
`
`adjusted after discharge or any curing after trajectory adjusting. Because CRUMP does not teach
`
`or suggest all features recited in independent claim 18, the rejection of independent claim 18
`
`should be withdrawn.
`
`In the Final Office Action, the Examiner suggested that CRUMP discloses all of the
`
`limitations of independent claim 18, but does not specifically address the limitations of post(cid:173)
`
`discharge trajectory adjustment or post-adjustment curing. In addition, the Examiner stated that
`
`"CRUMP further discloses that each strand (180) solidifies in space as it is dispensed from the
`
`nozzle (112)." See Final Office Action at 4-5. Because the strand (180) of CRUMP solidifies in
`
`space as it is dispensed, no opportunity exists for the post-discharge adjustment recited in
`
`independent claim 18.
`
`V.
`
`Claims 19-20 Rejection (CRUMP)
`
`In the Final Office Action, the Examiner rejected claims 19 and 20 as being anticipated
`
`by CRUMP. See Office Action at 3. Of these claims, claim 19 is independent.
`
`Independent claim 19, as currently amended, recites a method of manufacturing a three(cid:173)
`
`dimensional object that comprises, among other things, "discharging from a nozzle a first path;
`
`curing a first portion of the first path, leaving a second portion at least partially uncured;
`
`-9-
`
`Page 9 of 11
`
`Markforged Ex. 1020
`Markforged v. Continuous Composites, IPR2022-01218
`
`
`
`Application No. 15/267,956
`Attorney Docket No. 13087.0003-02000
`
`discharging a second path adjacent the first path; curing the second path; mechanically
`
`interlocking the second portion of the first path with the cured second path; and curing the
`
`second portion of the first path while the second portion of the first path is mechanically
`
`interlocked with the cured second path." Because CRUMP does not teach or suggest all features
`
`recited in independent claim 19, the rejection of independent claim 19 should be withdrawn.
`
`In the Final Office Action, the Examiner suggested that CRUMP discloses all of the
`
`limitations of independent claim 19. In particular, the Examiner indicated that CRUMP
`
`discloses that "multiple dispensing materials are simultaneously discharged through a
`
`nozzle .... wherein the strands are interlocked." While this may be true, CRUMP does not
`
`disclose leaving a portion of a discharged path at least partially uncured, subsequently
`
`mechanically interlocking the portion with another already cured path, and thereafter curing the
`
`portion, as required by independent claim 19.
`
`Dependent claim 20 should be allowed at least because of its dependency on independent
`
`claim 19, as well as for its own limitations.
`
`VI.
`
`Conclusions
`
`Applicant respectfully requests entry of the present amendment under the AFCP Program
`
`2.0. The Guidelines for Consideration of Responses After Final Rejection under 37 C.F.R. §
`
`1.1 l 6(b) under the AFCP Program 2.0 provide that "a response after final rejection should be
`
`entered ... [i]f [t]he amendment can be determined to place the application in condition for
`
`allowance with only a limited amount of further search or consideration .... " Under the AFCP
`
`Program 2.0, up to three additional hours of time are available to the Examiner to consider an
`
`amendment after a final rejection.
