Intellectual Property Case Study

Intellectual Property Case Study

The Case Prof. Andrews is a Professor within the School of Chemistry at the

University of the East Midlands (UoEM).

During the study of his Ph.D., Mr. Evans tried to synthesise a new drug aimed at selectively killing cancer cells, under the supervision of Prof. Andrews.

Upon analysis of the product of this reaction, Mr. Evans noticed that the reaction had not in fact yielded the expected product, but had instead lead to another compound, compound X.

Compound X showed no activity against the cancer cells for which the original compound was designed.

Following the disappointment that compound X was inactive against cancer cells, the compound was screened against a wide range of other drug targets available within the Medical School of UoEM by a final year project student, Miss Fall, who was working in the group of Dr. Brown.

The results of this drug target screen were very positive identifying several drug targets against which compound X was active.

This prompted Miss Fall to conduct a literature review to establish other compounds which are active against the newly identified drug targets of compound X, which showed that compound X may act as a new treatment for HIV/AIDS.

Prof. Andrews has worked in close collaboration for many years with a group in Australia, which is lead by his friend Dr. Cairns, who is interested in retroviral diseases including AIDS.

Both Prof. Andrews and Dr. Cairns attended a conference in the USA in 2007, where, over dinner with their wives, they discussed aspects of the work relating to compound X.

Mr. Evans found that the exact structure of compound X proved difficult to establish. He therefore asked many people within his department to help him determine the correct structure of the compound.

Eventually, Dr. Davies, who is one of the other academics within the Chemistry Department of UoEM was able to reveal the structure of compound X, which proved particularly challenging to determine exactly.

Some months later, Dr. Cairns contacted Prof. Andrews by e-mail. Part of this email read:

“With regard to the ‘unknown’ HIV/AIDS compound we discussed in L.A., I stumbled across some work in the French Journal of Chemistry from 1998 detailing some compounds which I thought were interesting – just thought you may be interested. The reference is....”

This e-mail prompted Prof. Andrews to conduct a more through literature review which revealed that the compounds published in the French journal disclosed compounds of similar structure to compound X, but that this article did not consider their potential use against HIV/AIDS, or any other biological targets.

These compounds were also synthesised by a different method to that used by Mr. Evans.

Prof. Andrews told his patent attorneys that they had found compounds similar in structure to compound X in the literature, and gave them the reference.

Subsequently the patent attorneys found that the French group had in fact been granted a patent in 2002 for the compounds they had made and their use as a herbicide.

UoEM filed for a provisional UK patent on the 1st of April 2007, which was followed up a year later with an international PCT patent application on the 1st of April 2008.

UoEM is now actively seeking to out-license the invention of compound X to a pharmaceutical company for development into a new treatment for HIV/AIDS.

The Scope of the Invention

Defining the scope of a new invention accurately is the key aspect of a patent and requires all the skills of a qualified patent attorney.

This is because the legal protection granted by the patent relies solely upon the claims defined by the patent attorney.

The strength and scope of the claims will determine the extent to which the inventor(s)/owners can pursue the full financial value of the monopoly granted under the patent, and avoid other parties questioning the validity of the invention for their own financial benefit.

In broad terms, what is the invention UoEM are trying to patent?

In broad terms, how should the patent attorney define Compound X?

1. Compound X defined by its exact structure

2. Compound X defined as broadly as possible by structure

3. Compound X defined as broadly as possible by structure, but so as not to overlap with that described in the French Journal of Chemistry or the French patent

4. Compound X defined by its application for the treatment of HIV/AIDS only

5. Two or more of the above

Patentability of an Invention

In order for a patent to be granted it must be new and it must contain an ‘inventive step’.

An idea is considered ‘inventive’ when it is “non-obvious to someone who is skilled in the art.”

Someone who is ‘skilled in the art’ may include a trained technician or a research student.

How could you argue that the claims of the UoEM patent application involve an ‘inventive step’?

1. Compound X has unexpected use as a drug

2. Compound X may be used to treat HIV/AIDS

5. Two or more of the above

Inventorship and Ownership of an Invention

It is necessary to name the inventors in a patent application and these names are published on the patent.

It is important that the inventors are correctly named.

Who are the “actual devisers” of the invention (i.e. the inventors)?

What is the most important concern to UoEM regarding the correct identification of the inventors on this patent

before the invention is licensed?

1 2 3 4 5

0% 0% 0%0%0%

1. UoEM needs to know to whom it needs to give the profits of the license

2. If UoEM does not correctly identify all of the inventors then it can invalidate the patent in Europe

3. If UoEM does not correctly identify all of the inventors then it can invalidate the patent in the US

4. Because UoEM knows that it is good for all of the named inventors to be able to claim recognition for being an inventor to further their careers and promote the University

5. Because an unnamed inventor may file their own application

Disclosure and Confidentiality

Avoiding disclosure of a new invention or technology is of key importance.

If the new invention is disclosed into the public domain or “made available to the public” this can affect whether a patent is granted.

What effect might the following scenarios have on the likelihood of UoEM’s patent being granted or on them finding a licensing partner?

How would a public disclosure of the invention affect the value of the licence UoEM may agree with a pharmaceutical company?

1 2 3 4 5

0% 0% 0%0%0%

1. It would have no effect on the licence

2. It would increase the value of the licence since more people will be aware of the invention and want the new drugs produced

3. It would decrease the value of the licence since the patent may no longer be valid

4. It would depend on the timing of the public disclosure

5. It would remove all value of the licence

Freedom-to-Operate

A patent is a negative right (i.e. it stops others from using the technology detailed in the patent claims).

As such, you may not in fact be able to use your own invention or technology since parts of your invention may rely upon using other people’s patented technology.

This is called your ‘freedom to operate’.

As a potential licensee, what would concern you most about your freedom to commercialise Compound X in the future?
