Meaning
Quantitative formulas determine the specific monetary compensation a court will award to a patent holder after a finding of infringement in intellectual property litigation. PRC Patent Law Article 65 provides a hierarchical set of calculation methods to ensure that damages are predictable and grounded in economic reality. It lists four sources for these numbers, starting with the actual loss suffered by the patentee and moving to the gain made by the infringer.
If neither of those metrics can be calculated with certainty, the law looks toward multiples of historical patent licensing fees. This section is the final objective of almost all IP enforcement actions because it converts the technical victory into a cash liability. It applies broadly to all patent categories and sets the upper limit for statutory damages when precise numbers are elusive.
Calculation Hierarchy
Priorities in selecting the logic for award amounts focus first on the direct financial records of the parties involved in the dispute. PRC Patent Law Article 65 dictates that the court must seek evidence of the sales volume decrease for the plaintiff during the period of infringement. If this figure is complicated by multiple market factors, the focus shifts to the infringer’s profit margins and the quantity of knock-off products they sold.
Judges often use accounting audits or tax records to establish these figures, looking for the specific contribution that the patented technology made to the item’s total value. This contribution factor ensures that a small patented screw does not lead to damages based on the whole price of a truck. This granular analysis seeks to avoid overcompensating the patent holder while still creating a strong financial barrier against opportunistic copying.
The logic remains consistent across different industries regardless of the technological complexity.
Licensing Multiple
Reasonable royalties offer a fallback mechanism when both sets of corporate books are too complex or incomplete to establish clear profit gaps. Under PRC Patent Law Article 65, the judge can refer to previous contracts where the patent holder licensed their rights to legitimate third parties. The damage award is then typically set at between one and three times that historical royalty rate.
This approach serves as a penalty for the infringer who failed to negotiate a legal license in good time. It relies on the presence of actual licensing activity, which acts as a market benchmark for the technology’s real-world worth. For startup firms that have not yet issued licenses, this method is unavailable, pushing them toward the other calculation paths.
The use of an established multiplier turns the license into a yardstick that is difficult for defendants to challenge. It provides a quick way to finish cases without year-long forensic accounting investigations.
Statutory Cap
Maximum limits for court-ordered payments exist to handle cases where no reliable data on sales, gains or licenses can be found. PRC Patent Law Article 65 was recently updated to raise the ceiling for statutory damages, which can now reach several million units of the local currency in extreme cases. This discretion allows judges to punish bad-faith infringers who delete their server logs or operate in the shadow economy to avoid detection.
The amount is decided based on the intentionality of the breach, the duration of the activity and the breadth of the geographical area where sales occurred. Even without hard receipts, the holder can expect a minimum baseline payment to cover their litigation costs and basic losses. This final safety net ensures that every proven patent violation results in at least some financial consequence for the wrongdoer.
The presence of this cap encourages defendants to settle early if they know their actual profits were high enough to exceed the limit.
