Whereas the variety of revealed patent functions for superconducting quantum computing typically displays a wholesome progress pattern, there’s a noticeable slight slowdown in 2023.
Patent software publication charges for each photonic and trapped ion quantum computing have been quickly growing. Topological quantum computing skilled a slight lower in patent publications in 2023. Notably, quantum dot expertise reached a peak in patent software publications in 2019, adopted by a downward pattern, probably indicating waning curiosity on this space.
Regardless of their small numbers, patent functions for impartial atom, NMR, and nitrogen emptiness quantum computing have seen a fast enhance in recent times. Notably, the expansion sample in impartial atom quantum computing carefully mirrors that of photonic and trapped ion quantum computing, however with a three-year delay. This pattern signifies the potential of impartial atom quantum computing to turn out to be a mainstream method.
The next chart depicts the variety of patent functions for every mainstream quantum computing modality, as revealed by main patent jurisdictions. Notably, though China has the very best general variety of quantum computing patent functions, the US leads in patent filings particular to every fundamental bodily realization method. This may occasionally counsel that the U.S. leads in R&D actions for quantum {hardware}, whereas China focuses extra on quantum software program and functions of quantum computer systems.
Firms from completely different international locations exhibit various emphases on completely different quantum computing modalities. For example, the variety of U.S. patent publications dominates in photonic and quantum dot applied sciences, whereas Chinese language publications are notably aggressive in superconducting, trapped ion, and topological quantum computing. European patent publications show a extra balanced distribution throughout numerous modalities, whereas Japanese filings show a specific focus on superconducting and photonic applied sciences.
This put up additionally examines the extent to which bodily realization of quantum computing is referenced in patent functions. Among the many patent functions that point out not less than one bodily realization modality, it’s discovered that 24% of those functions incorporate key phrase(s) related to not less than one modality of their impartial claims, probably limiting the patent’s scope to a specific modality. In the meantime, 54% embrace a modality in dependent claims however not in impartial claims, indicating that the expertise is likely to be appropriate for numerous quantum computing sorts, with out confining the patent to a single modality. Lastly, 22% of the functions focus on bodily realization within the specification however omit them from the claims, suggesting that these patents concentrate on areas apart from the bodily realization of quantum computer systems and point out it primarily as background info or enabling disclosure.
Dialogue
The speed of patenting in quantum computing is escalating, mirroring the fast progress of the sector. As producers start to introduce commercially viable quantum computer systems that outperform classical counterparts and generate substantial income, they are going to start to turn out to be targets for patent assertions, making the competitors within the realm of mental property more and more related.
Patents in regards to the bodily realization of quantum computer systems are probably influential as they embody foundational applied sciences utilized throughout the whole industrial chain which are typically simple to detect and laborious to design round. But, patents particularly concentrating on bodily realization modalities of quantum computer systems account for a small fraction (lower than 10%) of all quantum computing patents. The quantity of patent functions for many modalities remains to be modest in comparison with extra established industries. This comparatively open discipline presents distinctive alternatives for corporations to safe broad and impactful patents.
Even for innovations not centered on a particular bodily realization of quantum computer systems, detailing {hardware} options might be advantageous. Such disclosures not solely fulfill the requirement for an enabling written description but additionally supplies choices for successfully differentiating prior artwork that lacks corresponding disclosures. Disclosures as to how higher-level strategies or functions might be tailored or optimized for explicit bodily realizations turns into notably invaluable on this context, providing strategic advantages in highlighting the patent’s novelty and positioning the patent for potential assertions.
Patent information reveal disparate maturity ranges amongst quantum computing modalities. Superconducting applied sciences present a lead of two to a few years over different key approaches like photonic and trapped-ion applied sciences. Concurrently, rising fields resembling impartial atom quantum computing are seeing an increase in patent actions. In a discipline rife with uncertainty, the place the long run may favor a single modality or foster the coexistence or integration of a number of ones, this different patent panorama turns into a crucial consider strategic patent planning. Whereas securing sturdy patent safety within the main modality is important for achievement, investing in lesser-protected areas might yield disproportionately excessive returns.
The patent information additionally underscores intense international competitors in quantum computing, with the US main in patent functions for all key modalities, but typically holding a smaller share than the mixed whole of China and Europe. Given the notion of quantum computing as a matter associated to nationwide safety, corporations might encounter regulatory hurdles in getting into sure markets. In response, they could take into account patent licensing as a substitute income supply in inaccessible markets. In such circumstances, goal licensees will acquire appreciable leverage if they’re able to counter-asserting patents in opponents’ house markets. Consequently, it could be strategically useful for corporations to hunt patent safety not solely of their operational markets but additionally within the house international locations of their main opponents.
