Commitments and Contingencies	6. Commitments and Contingencies Operating Lease Commitments. Our operating lease commitments consist primarily of our facility lease and various office and computer equipment leases. As of September 29, 2018, our total future minimum lease payments through fiscal year 2022 under current operating leases was approximately $4.9 million. Purchase Commitments. Our purchase commitments consist primarily of non-cancellable purchase commitments with vendors to manufacture certain components and ophthalmic instrumentation. As of September 29, 2018, our future minimum payments through fiscal year 2019 for our purchase commitments was approximately $13.4 million. Indemnities. We enter into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, we indemnify, hold harmless, and agree to reimburse the indemnified parties for losses suffered or incurred by the indemnified parties (generally our business partners or customers) in connection with any trade secret, copyright, patent or other intellectual property infringement claim by any third-party with respect to our products. The term of these indemnification agreements is generally perpetual any time after the execution of the agreement. The maximum potential amount of future payments the we could be required to make under these agreements is not determinable. We have never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, we believe the estimated fair value of these agreements is minimal. We have entered into indemnification agreements with our directors and officers that may require us to indemnify our directors and officers against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct of a culpable nature. These agreements also require us to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified and to make good faith determination whether or not it is practicable for us to obtain directors and officers insurance. We currently have directors and officers liability insurance. Legal Proceedings. In January 2018, we filed a lawsuit against Quantel Medical, S.A., Quantel USA, Inc., and Quantel, S.A. (collectively, “Quantel”) in the U.S. District Court for the Northern District of California. The lawsuit alleges that Quantel products infringe U.S. Patent No. 7,771,417, that Quantel breached an earlier agreement between Quantel and the Company, and that Quantel has infringed upon the Company’s MicroPulse® trademark, Registration No. 4550188 on the principal register. Quantel previously had a limited license to the asserted Company patent and trademark. Our complaint filed in connection with this matter asserts that the license was terminated in early 2017 for material breach, but that Quantel continued to use our intellectual property without authorization. On March 8, 2017, OD-OS GmbH noticed an opposition to the Company’s European Patent No. currently EP 1 856 774 at the European Patent Office (“EPO”). On June 8, 2018, Quantel intervened in the Opposition. Oral proceedings on the opposition took place on July 13, 2018. At the conclusion of those proceedings, the EPO’s Opposition Division communicated that it would move to revoke the patent. The formal written decision from the Opposition Division was issued on October 1, 2018. The Company filed its notice of appeal on October 10, 2018. In late May of 2018, Quantel applied to the Paris District Court in Paris, France for a ruling that its products do not infringe the French Part of Iridex’s European Patent at issue in the opposition, EP 1 856 774. A scheduling conference is set for November 6, 2018. In addition, from time to time, we may be involved in legal proceedings arising in the ordinary course of business. Although the results of litigation and claims cannot be predicted with certainty, we currently believe that the final outcome of these ordinary course matters will not have a material adverse effect on our business, operating results, financial condition or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.
