In this second article in our ‘How to…’ series, we reflect on what we learned from Mugdha Joshi, IP & Licensing expert at Kings College London, in her training session on Intellectual Property.
What is Intellectual Property?
Intellectual Property (IP) is a term that refers to the ‘creations of the mind’ such as inventions, works of art and symbols, names and images used in commerce.
Types of IP
Patents - Works to prevent another person from being able to use the same invention. They cover how inventions work, how they do it, what they are made of and how they are made. A patent lasts for 20 years and it must be renewed on its fourth anniversary. It then must be renewed every year. After 20 years the patent is given to the public. To qualify for a patent, the invention needs to meet the following criteria:
- The invention needs to be undisclosed and not in the public domain before the date of filing. However, any disclosure under a non-disclosure agreement is fine.
- Your idea needs an inventive step that is not obvious to someone with knowledge of the subject.
- It must be a solution to a problem.
- It must be something that can be made and not just speculative.
Copyrights – Protects work created by their author. It must be the author’s own intellectual creation and not have been copied from somewhere else.
Designs – This refers to the aesthetic aspects of an article. It protects 3D objects, or the designs applied to them.
Trademarks – A distinctive sign that identifies certain goods or properties provided by an individual or a company.
Commercialisation of IP
The commercialisation process involves:
- Market analysis - What does your product solve? Why is it better than your competition? Who wants it and why? What are its limitations? What is the development time? (Click here for more on marketing).
- Due Diligence - In-depth research of your company and invention and will include schedules of patents, copyrights and trademarks
- IP protection - Prior art search and patent attorney. You must ensure there is no evidence of your idea already being known.
- Proof of concept fund
- Marketing - Reaching out to companies and sending non-confidential flyers
- Licensing - What’s down the pipeline? Exclusive or non-exclusive licence? What obligations are there, e.g. development milestones?
- Spit-out creation - What do venture capitalists look for? They will want to see all your documentation that demonstrates that you meet various requirements. They will want to see your granted patents. It is a good idea to have a portfolio with multiple aspects of the product covered. They want to see that your product and company is professionally managed and that there are no issues of contested ownership or opposition.
The Bright SCIdea Challenge 2020 Final
SCI are unable to protect any intellectual property submitted as part of the competition. It is in your best interest to not disclose any information that could give away key aspects of your innovation for others to reproduce.
With an ever-increasing demand for data storage, the race is on to develop new materials that offer greater storage density. Researchers have identified a host of exotic materials that use new ways to pack ‘1’s and ‘0’s into ever-smaller spaces.
And, while many of them are still lab curiosities, they offer the potential to improve data storage density by 100 times or more.
Having a moment

The principle behind many storage media is to use magnetic ‘read’ and ‘write’ heads, an idea also exploited by many of these new technologies – albeit on a much smaller scale.
A good example is recent work from Manchester University, UK, where researchers have raised the temperature at which ‘single molecule magnets’ can be magnetised. Single-molecule magnets could have 100 times the data storage density of existing memory devices.
In theory, any molecular entity can be used to store data as reversing its polarity can switch it from a ‘1’ to a ‘0’. In this case, instead of reading and writing areas of a magnetic disk, the researchers have created single molecules that exhibit magnetic ‘hysteresis’ – a prerequisite for data storage.

‘You need a molecule that has its magnetic moment in two directions,’ says Nick Chilton, Ramsay Memorial research fellow in the school of chemistry. ‘To realise this in a single molecule, you need very specific conditions.’
In addition to having a strong magnetic moment, the molecule needs a slow relaxation time – that is, the time it takes for the molecule to ‘flip’ naturally from a ‘1’ to a ‘0’. ‘If this time is effectively indefinite, it would be useful for data storage,’ he says.
The key is that the molecule itself must have a magnetic moment. So, while a bulk substance such as iron oxide is ‘magnetic’, individual iron oxide particles are not.

Chilton and his colleagues have identified and synthesised a single-molecule magnet – a dysprosium atom, sandwiched between two cyclopentadienyl rings – that can be magnetised at 60K. This is 46K higher than any previous single-molecule magnet – and only 17K below the temperature of liquid nitrogen.
Being able to work with liquid nitrogen – rather than liquid helium – would bring the cost of a storage device down dramatically, says Chilton. To do this, the researchers must now model and make new structures that will work at 77K or higher.
Skyrmions may sound like a new adversary for Doctor Who, but they are actually another swirl-like magnetic entity that could be used to represent a bit of digital data.
Scientists at the Max Born Institute (MBI), Germany – in collaboration with colleagues from Massachusetts Institute of Technology, US – have devised a way to generate skyrmions in a controllable way, by building a ‘racetrack’ nanowire memory device that might in future be incorporated into a conventional memory chip.
‘Skyrmions can be conceived as particles – because that’s how they act,’ says Bastian Pfau, a postdoctoral researcher at MBI, as they are generated using a current pulse.
‘Earlier research put a lot of current pulses through a racetrack and created a skyrmion randomly,’ he says. ‘We’ve created them in a controlled and integrated way: they’re created on the racetrack exactly where you want them.’

In fact, skyrmions can be both created and moved using current pulses – but the pulse for creating them is slightly stronger than the one that moves them. The advantage of using a current pulse is that it requires no moving parts.
The resulting racetrack is a three-layer nanowire about 20nm thick – a structure that will hold around 100 skyrmions along a one-micron length of wire.
While the current research is done ‘in the plane’ with the nanowires held horizontally, Pfau says that in the future, wires could be stacked vertically in an array to boost storage capacity. ‘This would increase the storage density by 100. But this is in the future and nobody has made a strip line that’s vertical yet.’

‘The whole function depends on how you create the multi-layer,’ he says. To stand any chance of being commercialised, which might take six or eight years, Pfau says that new materials will be needed.
However, he is confident this will happen – and that the technology can be merged with ‘conventional’ electronic devices.
