Office Action

§112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Information Disclosure Statement No IDS has been filed in this application. Applicant is reminded that each individual associated with the filing and prosecution of a patent application has a duty of candor and good faith in dealing with the U.S. Patent and Trademark Office, which includes a duty to disclose to the Office all information known to that individual to be material to patentability. 37 CFR 1.56. 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 6-8 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. Regarding claim 6, the phrase “sandwich-like” renders the claim(s) indefinite because the claim(s) include(s) elements not actually disclosed (those encompassed by "or the like"), thereby rendering the scope of the claim(s) unascertainable. See MPEP § 2173.05(d). Claims 7-8 depend on claim 6 and are therefore, rejected for the same reason. Allowable Subject Matter Claims 1-5 and 9-10 are allowed. The following is an examiner’s statement of reasons for allowance: With respect to independent claim 1, the prior art does not disclose, in the claimed environment, a biosensor chip as arranged in the instant claim. Huff et al. US 2018/0275088 is believed to be the closest prior art. Huff, however, does not teach a conjugate pad, a conjugate pad groove connected to an optical fiber channel, a glue injection hole or a glue injection groove required of the instant claims. Similarly, Ohtsuka US 2010/0047820 does not teach an optical fiber, a conjugate pad, a conjugate pad groove connected to an optical fiber channel, a glue injection hole or a glue injection groove required of the instant claims. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to LYDIA EDWARDS whose telephone number is (571)270-3242.
