Office Action

§102
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 . Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim 1 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Van Den Berg et al (US 2019/0362936; herein Van Den Berg). Regarding claim 1: Van Den Berg teaches the apparatus of claim 1 in the Abstract, paragraphs 0026-0037, and Figures 1-4. There is a power supply (paragraph 0032) which would have a cathode and anode. The electron 102 is biased by the power supply, otherwise it would not operate. There is a plasma source 160, a powder bed 123, and a controller 110. The controller operates the apparatus as claimed in the Abstract and paragraphs 0027-0028. The mitigation occurs as claimed per paragraphs 0036-0037 and Figures 3 and 4.
