‘627 Patent Reexamination
In September 2011, Smart Modular submitted a request for an Inter Partes Reexamination by the USPTO of the Company’s U.S. Patent No. 7,864,627 (the “‘627 patent”), related to the ‘912 patent, alleging that the ‘627 patent is invalid and requesting that the USPTO reject the patent’s claims. On November 16, 2011, the USPTO granted Smart Modular’s request and initiated reexamination. By June 27, 2014, the USPTO’s patent examiner had rejected all of the ‘627 patent’s claims. The Company appealed the examiner’s rejections to the PTAB, and on May 31, 2016, the PTAB issued a decision affirming some of the examiner’s rejections. On July 31, 2016, the Company submitted a request to the PTAB to reopen prosecution before the examiner to amend the claims. On February 9, 2017, the PTAB granted the Company’s request to reopen prosecution and remanded the proceeding to the examiner to consider the patentability of the amended claims in view of the PTAB’s May 31, 2016 decision and comments from Smart Modular. On October 2, 2017, the examiner issued a determination that the amended claims should also be rejected. On June 1, 2018, the PTAB reversed the examiner and found the amended claims to be patentable. Smart Modular did not appeal this latest PTAB decision to the Federal Circuit. On October 3, 2018, the USPTO issued a Notice of Intent to Issue a Reexam Certificate, and on November 5, 2018, the USPTO issued Reexamination Certificate No. 7,864,627 concluding the reexamination. The original ‘627 patent had eighteen claims, and during the reexamination, five were canceled (claims 1, 4, 15, 19, 20) and the remaining fifteen were amended (claims 2, 3, 5-12, 14-18) into their current form as issued in the reexamination certificate. Accruals have not been recorded for loss contingencies related to the ‘627 patent reexamination proceedings because it is not probable that a loss has been incurred and the amount of any such loss cannot be reasonably estimated.
‘274 Patent Reexamination
As noted above, in April 2010 and June 2010, Inphi submitted requests for an Inter Partes Reexamination of the ‘274 patent by the USPTO. On August 27, 2010, the request was granted. In March 2012 and June 2012, the USPTO issued an ACP and a RAN, respectively, each of which confirmed the patentability of many of the ‘274 patent’s claims. The parties involved filed various notices of appeal, responses and requests, and on November 20, 2013, the PTAB held a hearing on such appeals. On January 16, 2014, the PTAB issued a decision affirming the examiner in part but reversing the examiner on new grounds and rejecting all of the patent’s claims. On September 11, 2015, the USPTO examiner issued a determination rejecting the amended claims. On January 23, 2017, the USPTO granted-in-part the Company’s petition to enter comments in support of its positions in the proceeding. On May 9, 2017, the PTAB issued a decision on appeal affirming the rejection of all claims. Netlist requested rehearing of the PTAB’s decision on June 6, 2017. The PTAB denied the rehearing request on August 8, 2017. On October 6, 2017, Netlist appealed the decision to the Court of Appeals for the Federal Circuit, which Netlist dismissed on March 19, 2018, thereby terminating the proceedings with the rejection of all ‘274 patent claims becoming final. Accruals have not been recorded for loss contingencies related to the ‘274 patent reexamination proceedings because it is not probable that a loss has been incurred and the amount of any such loss cannot be reasonably estimated.
Smart Modular ‘295 Patent Litigation and Reexamination
On September 13, 2012, Smart Modular filed a patent infringement lawsuit against the Company in the U.S. District Court for the Eastern District of California (the “Eastern District Court”). The complaint alleges that the Company willfully infringes and actively induces the infringement of certain claims of U.S. Patent No. 8,250,295 (“the ‘295 patent”) issued to Smart Modular and seeks damages and injunctive relief. The Company answered Smart Modular’s complaint in October 2012, denying infringement of the ‘295 patent, asserting that the ‘295 patent is invalid and unenforceable, and asserting counterclaims against Smart Modular. Accruals have not been recorded for loss contingencies related to Smart Modular’s complaint because it is not probable that a loss has been incurred and the amount of any such loss cannot be reasonably estimated.
On December 7, 2012, the USPTO granted the Company’s request for the reexamination of the ‘295 patent. On April 29, 2014, the USPTO examiner issued an ACP confirming some claims and rejecting others, and on August 4, 2015, the examiner issued a RAN confirming all pending claims. On September 4, 2015, the Company appealed to the PTAB. The parties involved filed various notices of appeal, responses and requests, and on September 22, 2016, the PTAB held a hearing on such appeals. On November 14, 2016, the PTAB issued a decision reversing the examiner and rejected all of the pending claims. On January 23, 2017, Smart Modular filed a request to reopen prosecution. The parties had the opportunity present evidence and arguments and the examiner issued a determination on May 8, 2017, which
