Patents context for IP teams
In 1863, David Kirkaldy secured a patent (GB2970) for his Universal Testing Machine, a groundbreaking hydraulic apparatus designed to apply various mechanical tests—tensile, compressive, torsion, and bending—to diverse material samples. This invention laid the groundwork for what is now recognized as the materials informatics revolution.
Housed today in the Kirkaldy Testing Museum at 99 Southwark Street, London, the Universal Testing Machine remains a testament to Victorian engineering. Weighing over 100 tonnes, the machine was operational until the 1970s and was instrumental in testing components for landmark projects such as the original Wembley Stadium and the Skylon building. It also played a role in analyzing failed components from engineering disasters like the 1874 Tay Bridge collapse and the 1954 BOAC flight 781 explosion.
Key takeaways for materials informatics patents
- Confirm how the development affects patents ownership, enforcement, licensing, or portfolio records.
- Separate confirmed facts from legal interpretation before advising business teams.
- Map deadlines, affected assets, contracts, and evidence files to the responsible internal owner.
- Use the issue as a prompt for monitoring, filing strategy, dispute preparation, or member education.
Practical analysis
Kirkaldy’s career began in 1843 at the Napier Foundry Works in Glasgow amid the Industrial Revolution’s surge. Observing the rise of steel as a replacement for cast and wrought iron, he recognized the necessity of understanding this new material’s properties through rigorous testing. This insight led him to establish his own testing works in London in 1861, where he developed the Universal Testing Machine.
The machine’s versatility was its hallmark, capable of applying large forces with high sensitivity across samples of varying shapes and sizes. Kirkaldy’s 1863 patent came shortly after the 1852 Patents Act reforms, which unified the UK patent system and made patenting more accessible and affordable, fostering innovation during the industrial age.
Beyond the mechanical ingenuity, Kirkaldy’s most forward-thinking contribution was his emphasis on data collection and objective analysis—embodied in the workshop’s motto, “FACTS NOT OPINIONS.” He pioneered the systematic gathering and commodification of data from both successful and failed tests, a principle that resonates strongly with today’s materials informatics.
At the time, patents could encompass multiple inventive concepts, and Kirkaldy’s claims covered both the machine and generic mechanical elements like levers and pistons. However, his data-driven methods were not recognized as patentable inventions, reflecting the era’s limited view of what constituted patentable subject matter.
In contrast, contemporary patent law requires claims to demonstrate a “technical effect.” Pure data collection and analysis claims are generally unprotectable unless tied to specific technical applications, such as optimizing alloy compositions or microstructures to achieve desired mechanical properties and manufacturing components accordingly. Such claims can now be granted in jurisdictions like the UK.
Kirkaldy’s legacy is evident in the thriving field of materials informatics today, where AI and machine learning accelerate materials research by analyzing vast datasets to predict optimal properties efficiently. This data-driven approach contrasts with traditional experimental or computational methods, which are often costly and time-consuming.
Since 2016, patent applications in materials informatics have surged five-fold, reflecting rapid innovation in data capture, storage, analysis techniques, and user-system interactions. This growth presents both opportunities and challenges for innovators navigating the evolving patent landscape.
The phrase “FACTS NOT OPINIONS” that greeted visitors to Kirkaldy’s workshop symbolizes the enduring shift toward empirical, data-centric engineering that continues to drive materials science forward. Kirkaldy’s early innovations laid the foundation for this ongoing revolution.
