In this article for Managing Intellectual Property, Mathys & Squire Associate Alex Robinson provides expert commentary on whether the revised rules of procedure at the EPO’s Boards of Appeal are likely to improve efficiency.

Revised rules of procedure at the EPO’s Boards of Appeal and their focus on avoiding late amendments and submissions could see parties ‘front-load’ their arguments at an earlier stage, causing a headache for first instance divisions, lawyers say.

The revised rules were adopted after the latest meeting of the EPO’s oversight body, the Administrative Council (AC), at the end of June.

Among the changes are stricter measures for dealing with submissions made during an appeal and a tweaking of the rules on when cases can be remitted back to the decision of first instance.

The revised rules, intended to combat the EPO’s backlog, will come into force in January next year. Alex Robinson, patent attorney at Mathys & Squire in London, says the tightening up of amendments at the appeal stage could result in a “precautionary front-loading” of requests, amendments and supporting evidence into first instance proceedings.

Article 12 of the revised rules clarifies that any amendment to a party’s appeal case after it has filed its initial grounds of appeal will be “subject to the party’s justification and may be admitted only at the discretion of the board.”

Robinson says parties may take a precautionary approach in light of this and try to account for “every possible permutation of issues in documents filed in first instance proceedings.”

This, he says, would allow parties to keep the opportunity to address every possible point should the need arise during a subsequent appeal. He notes, however, that this could increase the workload of the first instance divisions.

Robinson says the boards were already quite strict on this, but that “by putting it into the black letter of the rules,” the EPO has taken away some of the discretion that the boards theoretically have under the current rules.

The new rules will not apply to cases where the grounds of appeal are filed before the start of 2020, or where a summons to oral proceedings has already been issued by then.

Robinson says this may prompt “a flurry of activity” in the next six months as attorneys whose cases would otherwise be subject to the new rules try and get in as many arguments and amendments as they can now, so as not to fall foul of any stringency in the revised rules.

Patent ping pong

A major reason behind the rule changes – approved during the AC meeting of June 26 to 27 – is to avoid first instance decisions being appealed and patents then entering a ‘ping-pong scenario’ between the first instance and appeal stages, adding to the office’s overall backlog.

Article 11 of the revised rules now says the board shall not remit a case unless ‘special reasons present themselves for doing so’.

Previously this part of the rules stated that the board shall remit a case to the department of first instance if fundamental deficiencies are apparent in the first instance proceedings, ‘unless special reasons present themselves for doing otherwise’.

Robinson notes that if a patentee appeals against a first instance decision, the boards will quite often send a case back, but that the new rules clarify that this will only happen if special procedural reasons are highlighted.

Robinson says: “The backlog is notorious and it’s a laudable objective to try and combat this. But some of the rules could be seen as using a sledgehammer to crack a nut.”

The EPO’s backlog is regularly bemoaned. However, critics have previously told Managing IP that the office’s latest strategic plan shows there is too much focus on trying to grant patents quickly rather than ensuring they are of sufficient quality.

The revised rules, although positive in limiting the scope for reassessment, could muddle things further by overloading first instance divisions with claims that may not be relevant at the time.

All roads lead to Rome, all Silk Roads lead to China. With the latest, most ambitious Chinese initiative dawning upon us, it is essential for IP right holders to factor in the changes and challenges that come along with the One Belt One Road (OBOR) strategy. 

What is the OBOR?

The OBOR is a Chinese strategy which was initiated in 2013. Its aim is to forge closer economic ties by linking Europe and Asia through an improved transport infrastructure, consisting mainly of new rail routes, called ‘belts’, and new maritime routes, confusingly called ‘roads’.

The strategy has gained popularity rapidly, with over 80 countries adhering to the overall initiative since 2013.

The threat

One of the ‘belts’ connects China with Europe, with trains arriving in Paris and London and one of the main ‘roads’ will start in China and reach Italy through the Suez Canal, connecting with ports in Singapore, Kuala Lumpur, Sri Lanka, Maldives, Seychelles and Africa on the way.

We are, therefore, witnessing the development of a fast transport system that joins together new production countries in Southeast Asia, Central Asia and Africa, with western countries of destination. Add in the lower costs of production, the increasing number of free-trade zones and the less stringent customs controls along the OBOR routes and you’ve got yourself a very favourable environment for counterfeiting and organised crime activities.

The maritime routes will remain cheaper and thus preferred by counterfeiters in some instances, while the new railways provide for much faster transport, which could serve as a more appropriate method of ferrying a wide range of ‘limited life’ goods, such as pharmaceuticals and foodstuffs.

UK, EU and the OBOR

The European Commission has stated that the EU will be the final destination for at least one-third of Chinese exports, with an estimated value in excess of $600 billion per year. By 2020, it is suggested that this could reach $1 trillion.

With the UK set to leave the EU, right holders are concerned that due to a potential bilateral trade deal with China, the UK will become the destination for huge volumes of counterfeit goods, but that the UK will not deploy the corresponding levels of additional customs control. Moreover, there are concerns that post-Brexit, the cooperation between EU and UK customs could suffer, with the EU limiting access to its information and intelligence.

The solution?

In light of all this, both EU and UK right holders call for long term, policy preparation for the development of the OBOR strategy. They urge the West to take the initiative and improve the customs control capacity at ports, free zones and rail stops, and lobby for better control and expertise in the Southeast Asian, Central Asian and Eastern European countries.

As for the relations between the UK and the EU, right holders believe it vital that the two parties take joint responsibility and work together to ensure safety and security, even after Brexit concludes. This will certainly be a work in progress and we will be sure to keep you updated as things progress.

IP rights are valuable business assets and can be an important source of financing.

Virtually everything your business creates, that sets it apart from your competitors, is likely to attract some form of intellectual property (IP). It is, therefore, important to understand the significance of IP to your business and how you go about protecting it.

Registered rights such as patents, trade marks and Registered Designs are reasonably widely familiar, but many businesses are unaware of their less tangible, unregistered IP rights, that exist automatically when something is created, and require no registration procedure. These could, in fact, be hugely valuable assets in their own right. Examples include copyright, unregistered design rights, database rights, semiconductor topography rights, know-how, confidential information and trade secrets. It is well known, for example, that the Coca Cola recipe is one of the most valuable trade secrets in the world, and continues to set them apart from their competitors.

Here are some top tips on how to protect your business’ IP:

Identify what IP your business has (or could have)

IP cannot add value or help to grow your business if you don’t know it’s there. It doesn’t just help to protect the things that make your business unique, but can also help you to raise crucial funds in order to grow your business.

Understand the unregistered IP rights that already exist within your business

It is rare for a business to have no IP at all, so even if you don’t have any registrable IP, you may have unregistered rights which can be just as valuable.

Know when to keep your ideas confidential and when it is safe to share them

Whether it’s a trade secret or a patentable invention, confidentiality can be a crucial part of your IP strategy.

Identify registrable IP to best protect the key USPs of your business

Strategic use of registered IP, such as patents, designs and trade marks, can protect your USPs to give you the competitive advantage to grow your business or attract investment.

Create an IP strategy to help secure funding 

Whether you need to borrow against the value of your IP, secure grant funding or attract investment, the right IP strategy can help, whereas a weak or non-existent IP strategy can be detrimental.

Understand the financing options available to you

Investment (whether private equity, angel, grant-based or even crowdfunding) is not the only way to finance your business for growth. Sometimes, a more attractive, and potentially quicker, option is to simply borrow the money you need to implement your growth strategy.

There are a number of ways for a small business to borrow money to fund their growth, such as these peer-to-peer websites: Funding Circle, RateSetter and Zopa.

However, not all businesses are sufficiently ‘creditworthy’ to consider what is essentially an unsecured loan, and this is where your IP could really help. IP rights are not only valuable business assets, but they can also be an important source of financing, because an ever-increasing number of lending institutions are extending their businesses to provide loans on the basis of IP, and some banks use IP assets as a credit enhancer, so knowledge and understanding of all of your IP rights could be crucial.

The management and protection of your IP should be seen as an ongoing discipline that is aligned with, and an integral part of, your business planning and strategy. Unless assets are protected, why would a third party invest if there is nothing to stop rivals from copying ideas and innovation?

You’ve had a great idea for a new product, so what do you do next?

In this article for Business & Innovation Magazine, we provide some top tips on raising funding in order to develop your business.

Some degree of product design is likely to be needed and you would expect the result of that, in the first instance, to be a minimum viable product (MVP) or working prototype that can be tested and ‘tweaked’ before the design is finalised for manufacture. This is, of course, a very simple description of what can often be a rather lengthy and complex journey which doesn’t end there, and, somehow, needs to be funded until sales revenue starts to cover the overheads.

In general, a new or growing business may (potentially) go through several rounds of funding to raise capital as it progresses along the road from concept to market, and these funding rounds can be broken into three broad categories, namely:

Raising capital can, in itself, be an arduous and frustrating process, but pre-seed funding, in particular, can be exceptionally difficult, because this is the capital you need for early-stage product development of an MVP, testing and finalising the product design. Not only that, you may need to pay for intellectual property registrations, market research, branding, etc. out of this capital, and yet you may not yet have anything viable for potential investors to buy into, nor anything tangible to borrow against.

There are a number of different ways to raise pre-seed funding, and although they are not all covered here, broadly speaking, many startup and scale-up ventures raise their pre-seed capital by one (or a combination) of:

With the exception of R&D tax credits, all successful bids for investment/funding are likely to have one thing in common: getting the message right.

So how do you go about getting your message across and attracting the right investors?

It is rarely possible to effectively do everything that needs to be done yourself, and it is crucial to have an effective core team and good relationships with at least a couple of credible service providers, such as an intellectual property attorney, product designer, branding specialist and marketing expert. It is this network of people that you want an investor to recognise as credible and sufficiently effective to take the business to the next stage.

Su Copeland of Priddey Marketing explains: “It isn’t easy to find the right investors, and doing so requires knowing where to find them and then having an attractive pitch.”

There is no doubt that the start-up journey is long and often complex. It almost always takes longer and costs more than you probably expected, but with the right people around you, and the right advice at the right time, you are much more likely to succeed in the end. Su has provided her top 10 tips below.

Top 10 tips for attracting investors

    • Convey your story
    • Make yourself attractive
    • Do your investor homework
    • Do your financial homework
    • Don’t just dive in
    • Tap into the government’s tax incentives and funding
    • Use well-targeted networking to find the right investor
    • Keep the conversation going
    • Tap into online funding
    • Draw on your wider team

In this article for Intellectual Property Magazine, Partner Chris Hamer and Associate Matthew Morton explore the bright future of plastic recycling technologies and the IP trends set to accelerate a greener environment.

Plastics are an increasingly important material, used across the world in sectors such as packaging, building and construction, the automotive sector and in electronics. The European Commission estimates that global production of plastics had increased to 322m tonnes by 2015, and expects that number to double in the next two decades.

The chemical stability of most plastic materials is one of the many properties that makes these materials so attractive, particularly in sectors such as packaging, where plastic is an ideal material for sealing and preserving foods or medicines for example.

Plastic packaging accounts for around 40% of plastic waste generated and it is difficult to imagine this is going to change in the future, as abandoning plastic in packaging would have serious consequences for the storage and supply of perishable resources worldwide.

The stability of plastic that has contributed to its success is now, however, becoming one of its principle weaknesses. The disposal of large amounts of waste plastic into natural environments, where its stability in many cases allows it to persist for hundreds of years, can lead to increasing build up of plastic waste in these environments. This issue is increasingly one of public concern, although it is likely that any solution to the problem will need to come from economic incentives driving industry towards recycling.

Plastics have been recycled since the 1970s, and such recycling has historically focused on the processing and reuse of plastics in much the same form as the plastic products they were recycled from. However, in some cases such recycled plastics can have inferior properties in comparison to new, so-called ‘virgin plastics’, and as a result, particularly when producing new plastic is relatively cheap, the economic incentives for recycling are not always obvious. Nonetheless, if plastic waste can be repurposed to fill a demand for other chemical products rather than trying to compete with virgin plastic, then this can offer an opportunity to change what is often simply treated as a waste stream into a valuable resource. Higher costs for plastic disposal could up the economic incentives for trying to generate profit from waste plastic in the near future.

Repurposed plastics

One way that certain plastics can be usefully recycled is by pyrolysis, by which plastics are heated to high temperatures in the absence of oxygen, thereby breaking the plastic down into simpler hydrocarbon products without combustion. These hydrocarbon pyrolysis products can then be used to replace, or blended with, hydrocarbon materials obtained by refining petroleum feedstocks. Hydrocarbon pyrolysis products can be used to blend with transportation fuels or can find use in lubricant base oils.

Lubricant base oils are typically combined with additives to tailor their properties to produce lubricating compositions such as motor oils or lubricants for use in industrial processes such as metalworking. Lubricant base oils are graded into different groups according to American Petroleum Institute standards, based on their composition and purity. Higher classification oils are traditionally obtained by carrying out treatments of mineral oil stocks, including hydrotreating to remove non-carbon impurities (Group I), further hydrocracking to reduce the size of hydrocarbon molecules in the oil and further improve purity (Group II) and hydroisomerisation to alter the structure of the hydrocarbon molecules to improve oil properties such as pour point and viscosity (Group III). While the ‘higher’ groups of oil can give improved performance, the steps to upgrade base mineral oils incur additional energy costs and increase capex to provide specialised treatment units. Synthetic oils are also produced to give tailored high-quality lubricant oils without using mineral oil feedstocks.

While the slow transition to electric powered vehicles, which do not require the same motor oils as internal combustion powered vehicles, could reduce lubricant demand, given the expense and lack of practical infrastructure for electric vehicles, it seems unlikely that demand for automotive lubricants will significantly decline in the short term. Electric cars nonetheless do need greases for lubricating their high-torque moving parts, which could potentially be supplemented by plastic-derived products. In addition, lubricants also find use in areas outside of the automotive sector and it has been suggested that despite movement towards electric cars, the opportunities for growth in the lubricants sector remain.

Polyolefin polymers such as polyethylene and polypropylene are made from very long chains of saturated hydrocarbons that in terms of molecular structure and overall composition are very similar to mineral oils, and by breaking down the hydrocarbon chains of the plastic into smaller parts, oils and waxes having similar properties to refined mineral oils can be obtained. Processed pyrolysis products can have very low sulfur, nitrogen and aromatics content compared to mineral oil sources, and so offer the potential for providing cleaner fuels. Oils and waxes obtained from plastics can also be used to provide feedstocks that can be refined and blended with existing products to produce high quality base oils. Other plastics that contain aromatic hydrocarbon rings, such as polyethylene terephthalate (PET) and polystyrene can also be decomposed to give liquid products containing aromatic hydrocarbons that have the potential for use in chemical industries. Polyvinyl chloride (PVC) poses some additional challenges when treated by pyrolysis due to formation of hydrochloric acid from the chlorine in the polymer, which can lead to corrosion of equipment.

Of course, a constant issue with all recycling technologies has been the feed material available, which tends to be unsorted and comprises a mix of different plastics. However, Professor Martin Atkins, chief executive of Green Lizard Technologies, who is involved in a planned 200,000 tonne waste plastic recycling plant in the US and a 50,000 tonne plant in the UK, states that recent technological developments have helped to address this particular issue.

Patent landscape

Growing interest in processes for repurposing plastic waste into higher value materials, such as oils and waxes for lubricants, can be monitored by observing patent filing trends in the area. Figure 1 shows numbers of international PCT applications found in a basic search for patent applications mentioning pyrolysis of plastics. While the number of applications appears to have remained relatively constant in recent years, it has roughly doubled over the past decade, increasing fourfold in the last 20 years.


Figure 1: Number of PCT applications and granted European applications by publication year that mention pyrolysis of plastics

 

One different way to look at the sector through patent trends is to look at how many patents are being granted each year. Taking a patent application from filing through to grant requires commitment on top of the cost of an initial filing, and so the number of patents going through to grant could better reflect the level of active commercial interest in the area. Figure 1, which also shows granted European patents, illustrates a sharp increase in the number of patents being granted the last few years. While it is not possible to say for certain what the reason for this is, it suggests an increasing desire for granted and enforceable patent protection in what seems to be a growing market.

Looking at the top filing entities in the field, many patent filings relating to plastic pyrolysis have historically come from large corporations such as Toshiba and Chevron, as well as BASF, who have recently announced a scheme to convert waste plastics into chemical feedstocks (Figure 2). In addition to large corporations, in recent times much of the activity in the plastic recycling field has come from relatively newer companies such as Trifol Resources, Recycling technologies and
Greenmantra Technologies.

Figure 2: Number of PCT patent filings by applicant (Search Output provided by Coller IP)

 

The trends in patent filings and the increased public interest in dealing with plastic waste in a more ‘green’ way point to a bright future for plastic recycling technologies.

For applicants filing patent applications at the UK Intellectual Property Office, it is also worth bearing in mind that technologies in this area will likely qualify for accelerated processing of patent applications via the free Green Channel programme.
