Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | Commitments and Contingencies Legal Matters The Company is not currently party to any legal matters to its knowledge. The Company is not aware of any other matters that would have a material impact on the Company’s financial position or results of operations. Royalties The Company contracts with third-party vendors to license tumor samples for development into PDX models and use in our pharmacology TOS business. These types of arrangements have an upfront fee ranging from nil to $30,000 per tumor sample depending on the successful growth of the tumor model and ability to develop them into a sellable product. The upfront costs are expensed as incurred. In addition, under certain agreements, for a limited period of time, the Company is subject to royalty payments if the licensed tumor models are used for sale in our TOS business, ranging from 2% to 20% of the contract price after recouping certain initiation costs. Some of these arrangements also set forth an annual minimum royalty due regardless of tumor models used for sale. For the three months ended January 31, 2025 and 2024, we have recognized approximately $117,000 and $114,000, respectively, in expense related to these royalty arrangements. For the nine months ended January 31, 2025 and 2024, we have recognized approximately $302,000 and $240,000, respectively, in expense related to these royalty arrangements.
