COMMITMENTS AND CONTINGENCIES	NOTE 7 - COMMITMENTS AND CONTINGENCIES *Licensing Agreements* On July 31, 2005, the Company had entered into a Technology License Agreement (“License Agreement”) with the University pursuant to which the University agreed to license to the Company patent rights and other intellectual property, among other things (the “Technologies”). The Technology License Agreement was amended on February 18, 2015 and currently does not provide for an expiration date. Pursuant to the License Agreement and its amendment, the Company obtained an exclusive worldwide license to make, have made, use, sell and import products based upon the Technologies, or to sublicense the Technologies in accordance with the terms of the License Agreement and amendment. In consideration, the Company agreed to pay to the University a royalty payment of 2.5% of net sales of any product based on the Technologies. If the Company elects to sublicense any rights under the License Agreement and amendment, the Company agrees to pay to the University 10% of any up-front sub-license fees for any sub-licenses that occurred on or after September 9, 2006, and, on behalf of the sub-licensee, 2.5% of net sales by the sub-licensee of all products based on the Technologies. The Company had no sales revenue for the three and nine months ended September 30, 2024 and 2023 and therefore was not subject to paying any royalties. In the event the Company fails to provide the University with semi-annual reports on the progress or fails to continue to make reasonable commercial efforts towards obtaining regulatory approval for products based on the Technologies, the University may convert our exclusive license into a non-exclusive arrangement. Interest on any amounts owed under the License Agreement and amendment will be at 3% per annum. All intellectual property rights resulting from the Technologies or improvements thereon will remain the property of the other inventors and/or Dr. Lovejoy, and/or the University, as the case may be. The Company has agreed to pay all out-of-pocket filing, prosecution and maintenance expenses in connection with any patents relating to the Technologies. In the case of infringement upon any patents relating to the Technologies, the Company may elect, at its own expense, to bring a cause of action asserting such infringement. In such a case, after deducting any legal expenses the Company may incur, any settlement proceeds will be subject to the 2.5% royalty payment owed to the University under the License Agreement and amendment. The patent applications were made in the name of Dr. Lovejoy and other inventors, but the Company’s exclusive, worldwide rights to such patent applications are included in the License Agreement and its amendment with the University. The Company maintains exclusive licensing agreements and it currently controls the five intellectual patent properties. *Legal Proceedings* From time to time we may be named in claims arising in the ordinary course of business. Currently, no legal proceedings, government actions, administrative actions, investigations or claims are pending against us or involve us that, in the opinion of our management, could reasonably be expected to have a material adverse effect on our business and financial condition. *Notice of Delisting* On July 24, 2024, the Company received a deficiency letter (the “Notification Letter”) from the Nasdaq Listing Qualifications (“Nasdaq”) stating that it is not in compliance with the minimum bid price requirements set forth in Nasdaq Listing Rule 5550(a)(2) for continued listing on The Nasdaq Capital Market. Nasdaq Listing Rule 5550(a)(2) requires listed securities to maintain a minimum bid price of $1.00 per share, and Nasdaq Listing Rule 5810(c)(3)(A) provides that a failure to meet the minimum bid price requirement exists if the deficiency continues for a period of 30 consecutive business days. Based on the closing bid price of the Company’s common stock for the 30 consecutive business days prior to the date of the Notification Letter, the Company no longer meets the minimum bid price requirement. The Notification Letter has no immediate effect on the listing or trading of the Company’s common stock on the Nasdaq Capital Market and, at this time, the common stock will continue to trade on the Nasdaq Capital Market under the symbol “PTIX”. The Notification Letter states that the Company has 180 calendar days, or until January 20, 2025, to regain compliance with Nasdaq Listing Rule 5550(a)(2). To regain compliance, the Company’s closing bid price of the Company’s common stock must have a closing bid price of at least $1.00 for a minimum of ten consecutive business days. The letter further states that in the event the Company does not regain compliance by January 20, 2025, the Company may be eligible for an additional 180 days if it meets the continued listing requirement for market value of publicly held shares and all other initial listing standards for Nasdaq, with the exception of the bid price requirement, and will need to provide written notice of its intention to cure the deficiency during the second compliance period. If the Company does not qualify for the second compliance period or fails to regain compliance during the second compliance period, Nasdaq will provide written notification to the Company that its common stock is subject to delisting. At that time, the Company may appeal the delisting determination to a hearings panel pursuant to the procedures set forth in the applicable Nasdaq Listing Rules. However, there can be no assurance that, if the Company does appeal the delisting determination by Nasdaq to the panel, such appeal would be successful.
