Revenue from Contract with Customer [Abstract]  
Revenue
(3) Revenue

Revenue is recognized when control of the promised products or services is transferred to customers. A majority of our revenue is recognized at the point in time when products are shipped or delivered and the point in time when services are delivered to customers. However, when we have entered into collaboration agreements with customers, we have typically been required to recognize revenue over time.

Performance Obligations

At March 31, 2024, we had $108,170 of unrecognized revenue comprised of deferred revenue, cancellable and non-cancellable customer order backlog, and customer deposits. This $108,170 excludes variable consideration totaling $46,000 which will not be included in contract transaction price for purposes of revenue recognition until management is able to conclude that it is probable that the inclusion of such amounts will not result in a subsequent significant reversal of the cumulative amount of revenue recognized. We expect to recognize approximately 95.3% of the $47,405 of the deferred revenue and customer deposits as revenue within the next twelve months, an additional 3.8% by the end of 2025 and the remaining balance thereafter.

Collaboration and Licensing Agreements

We enter into collaboration and licensing agreements with third parties. The nature of the activities to be performed and the consideration exchanged under these agreements varies on a contract-by-contract basis. We evaluate these agreements to determine whether they meet the definition of a customer relationship for which revenue should be recorded. These contracts may contain multiple performance obligations and may contain fees for licensing, research and development services, contingent milestone payments upon the achievement of contractual developmental criteria and/or royalty fees based on the licensees’ product revenue. We determine the revenue to be recognized for these agreements based on an evaluation of the distinct performance obligations; the identification and evaluation of material rights; the estimation of the amount of variable consideration to be included in transaction price, as well as the timing for inclusion of such variable consideration; and the amount of transaction price assigned to and the pattern of transfer of control for each distinct performance obligation. This typically results in the recognition of revenue over time using a cost-to-cost percentage of completion model to measure the progress of the transfer of control. The Company recognized $2,021 and $4,740 in revenue related to collaboration arrangements with customers for the three months ended March 31, 2024 and 2023, respectively.
