Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments The Company has commitments under certain license and development agreements, lease agreements, commitments related to renovating an existing facility for GMP, and debt agreements. Commitments under certain license and development agreements include annual payments, payments upon the achievement of certain milestones, and royalty payments based on net sales of licensed products (see Note 3). Commitments under lease agreements are future minimum lease payments (see Note 6). Commitments under debt agreements are the future payment of principal and accrued interest under the EB-5 Loan Agreement and the Loan and Security Agreement (see Note 8). Additionally, the Company does not expect to fulfill any commitments under the amended Co-Development, Supply and Commercialization Agreement with Bharat Biotech as a result of the termination of the COVAXIN program. Contingencies In June 2021, a securities class action lawsuit was filed against the Company and certain of its agents in the United States District Court for the Eastern District of Pennsylvania ("Court") (Case No. 2:21-cv-02725) that purported to state a claim for alleged violations of Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder, based on statements made by the Company concerning the announcement of the Company's decision to pursue the submission of a BLA for COVAXIN for adults ages 18 years and older rather than pursuing an EUA. In July 2021, a second securities class action lawsuit was filed against the Company and certain of its agents in the Court (Case No. 2:21-cv-03182) that also purported to state a claim for alleged violations of Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder, based on the same statements as the first complaint. In March 2022, the Court consolidated these two related securities class action lawsuits and appointed a lead plaintiff. In March 2024, the Third Circuit affirmed the Court's decision to dismiss with prejudice the consolidated securities class action lawsuits. In August 2021, a stockholder derivative lawsuit was filed derivatively on behalf of the Company against certain of its agents and the nominal defendant Ocugen in the Court (Case No. 2:21-cv-03876) that purported to state a claim for breach of fiduciary duty and contribution for violations of Sections 10(b) and 21(d) of the Exchange Act, based on facts and circumstances relating to the securities class action lawsuits and seeking contribution and indemnification in connection with claims asserted in the securities class action lawsuits. In September 2021, a second stockholder derivative lawsuit was filed derivatively on behalf of the Company against certain of its agents and the nominal defendant Ocugen in the Court (Case No. 2:21-cv-04169) that purported to state a claim for breach of fiduciary duties, unjust enrichment, abuse of control, waste of corporate assets, and contribution for violations of Sections 10(b) and 21(d) of the Exchange Act, based on the same allegations as the first complaint. The parties to both stockholder derivative lawsuits stipulated to the consolidation of the two stockholder derivative lawsuits. In April 2024, the Court dismissed without prejudice the consolidated stockholder derivative lawsuits. In April 2024, a securities class action lawsuit was filed against the Company and certain of its agents in the Court (Case No. 2:24-cv-01500) that purported to state a claim for alleged violations of Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder, based on statements made by the Company concerning the Company's previously-issued audited consolidated financial statements for each fiscal year beginning January 1, 2020 and its previously-issued unaudited condensed consolidated financial statements for each of the first three quarters in such years and the effectiveness of the Company's disclosure controls and procedures during each such period. The complaint seeks unspecified damages, interest, attorneys' fees, and other costs. In October 2024, the lead plaintiff filed an amended complaint, and in December 2024, the Company filed a motion to dismiss. In February 2025, the lead plaintiff filed an opposition to the motion to dismiss, and the Company intends to file a reply in support of the motion to dismiss by March 10, 2025. In May 2024, a stockholder derivative lawsuit was filed on behalf of the Company against certain of its agents and the nominal defendant Ocugen in the Court (Case No. 2:24-cv-02234) that purported to state a claim for breach of fiduciary duties, unjust enrichment, abuse of control, gross mismanagement, waste of corporate assets, violations of Section 14(a) of the Exchange Act, and contribution for violations of Sections 10(b) and 21(d) of the Exchange Act, based on the facts and circumstances relating to the securities class action and seeking damages and certain governance reforms in connection with claims asserted in the securities class action. In June 2024, the Court approved the parties’ joint stipulation for an order staying the derivative lawsuit pending resolution of a motion to dismiss in the related securities class action. In the third quarter of 2024, four additional stockholder derivative lawsuits were filed on behalf of the Company against certain of its agents and the nominal defendant Ocugen in the Court (Case Nos. 2:24-cv-03119, 2:24-cv-03209, 2:24-cv-04813, 2:24-cv-04864) asserting similar facts and claims as the first complaint, and in January 2025, a stockholder derivative lawsuit was filed on behalf of the Company against certain of its agents and the nominal defendant Ocugen in the Delaware Court of Chancery (Case No. 2025-0095) asserting similar facts and claims related to breaches of fiduciary duty, unjust enrichment and insider trading. The Company believes that the lawsuits are without merit and intends to vigorously defend against them. At this time, no assessment can be made as to their likely outcome or whether the outcome will be material to the Company. No information is available to indicate that it is probable that a loss has been incurred and can be reasonably estimated as of the date of the consolidated financial statements and, as such, no accrual for the loss has been recorded within the consolidated financial statements.
