The 3.7-year sweet spot: why technical standards have challenged science as the engine of patent value

*Suli Zheng, Knut Blind, Luqi Yang, Jingjing Guo are the authors of ‘Standard linkage and innovation value: Patent level evidence from V2X technology’, a landmark analysis published on Technovation in 2026 which bring forward the construct of standard linkage and timing of standard linkage to investigate the relationship of standardisation and innovation at the micro level.

What separates a revolutionary technology from one that gathers dust in a patent office? The answer increasingly lies in how an invention "recombines" existing knowledge. In the realm of high-stakes R&D, innovation is rarely a solitary flash of genius. It is a sophisticated process of standing on the shoulders of academic researchers and scientific theorists to solve complex problems.

However, a landmark deep-dive analysis published in Technovation, based on 1,400 Vehicle-to-Everything (V2X) patents, reveals a fundamental widening of the knowledge flows in the innovation process. In the fast-moving world of autonomous driving and intelligent transportation systems, the most valuable inventions are not only citing scientific papers. They are strategically linking themselves to technical standards. V2X technology, which bridges the gap between telecommunications and automotive engineering, offers a perfect window into why standards have become the new industry gold.

The research findings are stark: in the V2X field, standard citations in patent applications are approximately 2.6 times more frequent than scientific citations.

“This suggests that for modern inventors, technical specifications are a more vital source of formative knowledge than traditional scientific research” — Knut Blind, one of the key authors of the analysis, reveals. Knut Blind is Professor for Innovation Economics at the Technical University Berlin and Coordinator of the Business Unit Innovation and Regulation at the Fraunhofer Institute for Systems and Innovation Research ISI, which is one of the StandICT.eu consortium partners, leading the activities of the EUOS Training Academy.

"Standards often embody the collective wisdom and best practices of an industry... By referencing these standards, inventors can build upon established knowledge and avoid reinventing the wheel, leading to more efficient and effective inventions".

Is newer always better?

Conventional wisdom suggests that in technology, newer is always better. However, the data uncovers a sophisticated, non-linear relationship between the age of a standard and the value of the patent that cites it. This takes the form of an "inverted U-shape," where timing is everything. The research identifies a turning point: 3.7 years. Referencing a standard approximately 3.7 years after its publication yields the peak patent value. At this 3.7-year mark, the marginal effect of linkage reaches its zenith before the value begins to erode. Citing a standard too early is accompanied by uncertainty, while citing one too late often implies the technology has become mediocre or common knowledge. This 3.7-year turning point represents the moment when a standard is mature enough to provide a stable foundation but young enough to still drive competitive advantage.

The researchers' hypothesis development points to two competing latent mechanisms that determine an invention's ultimate impact:

• The innovation effect: Early linkage allows a patent to embed cutting-edge, formative knowledge consolidated in standards. This drives explorative breakthroughs that may become inherent to future dominant designs.
• The diffusion effect: This governs the market's consensus. Citing a standard in its infancy carries a high risk of selecting a specification that ultimately fails to gain widespread industry acceptance. Conversely, late linkage ensures the standard is a dominant design, but the potential for significant technological breakthroughs has already vanished.

“This stands in stark contrast to the phenomena that earlier integration with science confers a first-mover advantage. When developing new technologies on a standardised foundation, selecting the optimal timing is crucial” — Suli Zheng, lead researcher of this analysis, explains. Suli Zheng is a Professor at the School of Management Science and Engineering at China Jiliang University, who has dedicated over 15 years to research and education in the field of standardisation.

According to the empirical findings, a moderate timing allows an invention to balance these two forces for maximum efficacy.

"Inventions with a moderate timing of standard linkage are more likely to achieve the greatest impact — Knut Blind argues — on either side of this peak, the value of inventions diminishes." 

The insider’s edge: why participation is non-negotiable

While standards are public documents, the benefits are not distributed equally. The research highlights a massive strategic advantage for "insiders". These are firms that actively participate in Standard-Setting Organisations (SSOs).

These participants capture patent value significantly sooner and sustain that value for a longer period than non-participants. This insider’s edge is built on tacit knowledge, which is the implicit insights and best practices gained in the room where the standard was debated, as opposed to the explicit knowledge available in the published text to everyone else.

However, the most critical finding for strategy analysts is what we might call the "Outsider Penalty." For patent holders who do not participate in the standard-setting process, simply increasing their "Standard Linkage" can actually have a negative effect on patent value. Without the context of participation, outsiders often link to standards in a way that fails to produce high-value innovation.

“The strategic imperative is clear: to thrive, organisations must stop viewing R&D and standardisation as separate silos".

As Suli Zheng argues, this research demonstrates that in a standards-intensive economy, "R&D cannot exist in a vacuum. Instead, it must be precisely synchronised with the global standard lifecycle. The most successful firms will be those that master the timing of this integration and ensure they are in the room when those standards are being designed”.
