Claim Rejections - 35 USC § 112
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
Claims 1-10 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claim 1 recites “each linear fiducial comprises five or fewer rows of sample sites,” however, this limitation does not have support in the specification as filed. The specification discusses having three or more rows of sample sites and five rows of sample sites in paragraph [00114]. However, the specification does not disclose having less than three rows of sample sites (which also includes zero rows of sample sites). Therefore, the limitation that each linear fiducial comprises five or fewer rows (which includes zero, one or two rows) does not have support.
Claims 31-38 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claim 31 recites “each linear fiducial comprises five or fewer rows of sample sites,” however, this limitation does not have support in the specification as filed. The specification discusses having three or more rows of sample sites and five rows of sample sites in paragraph [00114]. However, the specification does not disclose having less than three rows of sample sites (which also includes zero rows of sample sites). Therefore, the limitation that each linear fiducial comprises five or fewer rows (which includes zero, one or two rows) does not have support.
Claims 39-46 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claim 39 recites “each linear fiducial comprises five or fewer rows of sample sites,” however, this limitation does not have support in the specification as filed. The specification discusses having three or more rows of sample sites and five rows of sample sites in paragraph [00114]. However, the specification does not disclose having less than three rows of sample sites (which also includes zero rows of sample sites). Therefore, the limitation that each linear fiducial comprises five or fewer rows (which includes zero, one or two rows) does not have support.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 1-10 and 31-46 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 1 recites that “each linear fiducial comprises five or fewer rows of sample sites,” however this limitation is unclear as this limitation would also include zero rows of sample sites. If there are zero rows of sample sites, it is unclear what would be defining each linear fiducial thereby rendering the claim as unclear. Claims 9-10 are rejected by virtue of their dependence on a rejected base claim.
Claim 31 recites that “each linear fiducial comprises five or fewer rows of sample sites,” however this limitation is unclear as this limitation would also include zero rows of sample sites. If there are zero rows of sample sites, it is unclear what would be defining each linear fiducial thereby rendering the claim as unclear. Claims 32-38 are rejected by virtue of their dependence on a rejected base claim.
Claim 39 recites that “each linear fiducial comprises five or fewer rows of sample sites,” however this limitation is unclear as this limitation would also include zero rows of sample sites. If there are zero rows of sample sites, it is unclear what would be defining each linear fiducial thereby rendering the claim as unclear. Claims 40-46 are rejected by virtue of their dependence on a rejected base claim.
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.

Response to Arguments
Applicant's arguments filed 12/18/2025 have been fully considered but they are not persuasive.
The examiner notes that the rejections above have been modified such that each linear fiducial has five or fewer rows of sample sites and blanks.
Regarding applicant’s argument that the Examiner stated that the missing wells where item 510 is the intended use of the claimed device. The examiner is not stating that the missing wells are the intended use of the claimed device, but rather when the blanks are empty sample sites are the intended use of the sample sites. While using the device, a person would be able to not fill certain sample sites in rows and arrive at the claimed invention. The filling or not filling of the wells is considered to be the intended use of the device and sample wells and therefore, as long as the sample wells are capable of being filled or not filled in accordance with the claim, the prior art would read on the instant claims.
Regarding applicant’s argument that Langlois does not contemplate having five or fewer rows of sample sites and blanks forming the linear fiducial is not found persuasive. The rejection has been modified above, such that the linear fiducials are now being considered as five rows of sample sites and thereby reading on the instant claims. The claim has not limited the number of linear fiducials and therefore there can be multiple linear fiducials where each linear fiducial comprises five or less rows of sample sites.
Regarding applicant’s argument that the linear fiducials are not vertically offset with respect to the course alignment fiducials is not found persuasive. The linear fiducials are considered to be the first five full horizontal rows of sample sites to the bottom of each of item 510 and as these are closer to the course alignment fiducials on one side compared to the other, the linear fiducials are considered to be vertically offset with the course alignment fiducials.
Regarding applicant’s argument of claim 46, as discussed above, the filling or not filling of the sample wells is considered to be the intended use of the sample wells. The sample wells could be filled in accordance to the claim and therefore renders the claim as anticipated.
