International Patent Forum 2013: a London conference

Add comment Comments (0)

I will be attending the International Patent Forum 2013, which will be held in London on the 16-17 April.

I normally deal with patent searching and documentation. It will be a change to listen to fourteen talks about changes in patent law, or about case law and other developments (and patent filing strategies), in specific regions or countries (including each of the BRICs). The emphasis is on how it all affects companies and their corporate strategy. This is of great importance to modern economies, of course.

I’m particularly looking forward to the talk on the new unitary patent and unified court for Europe, and the talk on the impact of the US patent reforms. I feel I'm not quite up to speed on both topics. The talks on the pharmaceutical sector, and on the smart phone wars, ought to be interesting too. I remember last time I attended coming away with lots of notes which I later followed up.

The conference will be run by the Managing Intellectual Property journal.

Blue screen film pioneer and inventor Petro Vlahos

Add comment Comments (0)

The inventor of the “blue screen” film technique as it is used today, Petro Vlahos, has died at the age of 96. This posting is based on the interesting BBC tribute to him. I am glad to say the article links to Google versions of two of his patents (this is unusual).

A blue screen is used in filming where actors are combined in film editing with action or other backgrounds to give a seamless effect. A not very good version was available when Vlahos was asked to see if he could improve the process. Some objects would appear to glow, and that was clearly annoying and hardly realistic. Vlahos later said that he spent six months thinking about it, much of it looking out at Hollywood Boulevard.

He came up with a technique that involved a matte which is transparent whenever the blue screen is used but is opaque in other sequences in the film. The blue, green and red parts are separated and then combined in a certain order. It seems that rather than the actors being superimposed on a background, which I'd assumed, it’s the other way round, which sounds mysterious to me (I do love the magic of the “movies” after all).

His Composite color photography patent was applied for in 1959 and the technique was first used in Ben Hur.

A more complicated variation was also patented as Composite photography utilizing sodium vapor illumination.

Both patents were assigned to the Motion Picture Research Council but the article states that this second technique was developed for Disney. Actors were filmed against a white background with sodium lamps which made a yellow glow bounce off the background.

The camera filmed two separate images (or “film stock”) simultaneously. A prism on the camera would cause one film stock to split the yellow light from other colours and send it to a black and white film stock to create a matte.

The other film stock would record in normal colour without any yellow glow. This produced a very clean effect, and was typically used when actors were apparently interacting with cartoon characters as in Mary Poppins and Bedknobs and Broomsticks.

Vlahos later formed a company, Ultimatte, to develop more techniques.

This is a list of Vlahos’ patents

The Smart Search format in the Espacenet patent database

Add comment Comments (0)

For some time the free Espacenet patent database has automatically opened at the Smart Search page, which I find slightly irritating as I normally want the Advanced search format.

I have used the Smart Search for entering patent numbers – this can be in the form 700000 or 70000 for example, or 190520000, and any relevant records will be retrieved. Filing numbers can also be requested. Using country codes such as US or GB is not required but is of course useful if many records are expected (such as lowish numbers). This ability to use numbers without codes used to be available in the Number Search format but this has been incorporated into Smart Search.

Another ability in Smart Search is the ability to use logical operators. This is the name for the ability to say things like “x must be present within 5 words of y”, so that there is a high chance that the words are closely related. Keyword searches would be in the title or the abstract (summary) area.

For example, suppose you are interested in the concept of an umbrella hat. One example is the rather striking drawing given below, by Friedrich Wielandt of Switzerland whose British patent 747154 was published in 1956.

 Rain protective head gear rain hat patent image

If you ask for “umbrella hat” you get 31 hits. If you ask for the words to be no more than 5 words apart you get 284. These would, admittedly, include some “false drops” such as the unwanted phrase “umbrella fabric is arranged between the hat body” which is from a Chinese specification

You can try reducing the 5 word rule to 3 (I personally would never make it less) which in this case would cut the number found to 262, a small loss. Simply using the words in the title or abstract field in the Advanced search, linked by “and”, gives 369 hits.

Results would presumably vary from one subject area to another, and would also depend on the ways words could relate to each other – “light” for example means illumination but also an absence of weight, and there would be odd results in many cases if that word was used. 

Greater precision nearly always means a loss of relevant material, and tools are never a substitute for using your judgment, which in turn depends on what you or a client wants and expects.

Smart Search uses codes to express these operators. The formula used above is:

umbrella prox/distance<5 hat

There is also this looser, but in a way more specific as it ties the words to use within the same sentence, code:

umbrella prox/unit=sentence hat

You could also add a country code such as “and pn=us” if you wanted the search limited to US publications. It is a pity that these codes are hardly intuitive and must be remembered or written down.

It is also a good idea to add truncation symbols: # means one extra character must be present, ? no character or one character (used for most plurals), while * indicates that any number of characters can follow (used, generally, for verbs).

My impression is that most if not all of the other possibilities in Smart Search are already catered for by using Boolean operators such as OR, AND, NOT, or by string searching with words included within quotes to show that they must be found in the same order.

Consultation on patent law harmonisation

Add comment Comments (0)

The UK IPO is inviting interested parties to complete a detailed questionnaire (36 pages including notes) as part of a consultation on patent law harmonization.

It is called the Tegernsee Experts Group – Informal Consultation on International Patent Law Harmonisation and replies are requested by the 1 March 2013.

It is part of an international effort to sort out and harmonise four aspects of patent law and procedure. These are

 Grace periods. Should it be permitted to have a “grace period” during which disclosure of an invention is allowed before filing a patent, which establishes the novelty “priority” filing. The USA for one allows domestic applicants to use the grace period.

 Publication at 18 months. At present most countries publish patent applications 18 months after the same priority date. Applicants have the right to file for foreign rights within 12 months of the priority date. Is this timing correct or should the timescale be altered.

 Treatment of conflicting applications. Because publication occurs 18 months after the priority filing, sometimes an application is anticipated by another application made months before, that neither the patent office nor the later applicant knew about. What should be allowed.

 Prior user rights. This is about the right to continue to use an invention if that was being done before someone else filed a patent for the invention. Has there been actual use or only preparations for use.

This looks like a very interesting amd important consultation and I would encourage interested parties to reply.

The Patent Box: tax breaks for UK innovation

Add comment Comments (0)

From the 1 April 2013 UK companies will be able to claim a corporation tax break on profits from patents in what is called the “Patent Box” scheme. HM Revenue and Customs have a page explaining how it works. 

Here is my summary of the main provisions. It is vital that anyone interested reads the full details to check if they are eligible.

The companies must either own the patents or have exclusive licenses for their use; must have worked on their development (or a related company must have done so); and must be making a profit from the patents.

The relief will be phased in over several years to achieve a tax rate of 10% on profits from patents. At present UK corporation tax is 24%, coming down to 23% this year. The details are quite complicated, with the following formula and notes being quoted in the website:

RP × FY% × ((MR - IPR) ÷ MR)

In the formula:

•RP is the profits of a company's trade relevant to Patent Box

•FY% is the appropriate percentage for each financial year

•MR is the main rate of Corporation Tax

•IPR is the reduced rate of 10 per cent

A couple of examples are given on the website of how it might work out.

The article The new Patent Box regime and corporate tax reform in the UK, published in International Tax Journal, September-October 2012, pages 51-58, gives many details and suggests that pharmaceutical and biotech companies in particular would find the scheme attractive (as so much of the value in their products depends on patents). I found it in the database Business Source Complete, which we subscribe to for the use of our readers in the Business & IP Centre.

The No!No! ® hair removal invention

Add comment Comments (0)

There has been a lot of TV advertising for an electrical hair removal device with the unusual name of no!no!®.

It uses heated wires to sever body hair, and the claim is that it is virtually painless -- unlike, so I hear, waxing. One thing that puzzled me was that in my hit list on Google’s UK search engine I got at the top of the list for the query “no no”...

NO NO Hair® Official Site

This suggests that the trade mark is No No Hair. Not true – No!No! was registered as a European trade mark in 2008 by Radiancy, Inc., an American company, for Class 3, including “hair lotions; dentifrices; creams and lotions” and also, separately, for Class 8 including “depilatory appliances”. There are 45 Nice Classes, and any applications will be for specified products or services within one or more class.

There are similar registrations in the US such as for “Thermodynamic heat conduction based electric hair shavers for aesthetic purposes”.

In fact the ® icon is not used on the No!No! website I found, something that is highly advisable as it might be thought to imply that they are using an unregistered trade mark (TM), a much weaker right.

Radiancy, Inc. is based in Orangeburg, S.C. The Orbis database, which our Business & IP Centre subscribes to, tells me that the “global ultimate owner” is PhotoMedex, Inc. which is in Pennsylvania and which describes itself as a “Global Skin Health Solutions company”.

In 2011 Radiancy, Inc. had $1.2 million in revenue (no profit figures were given) and 10 employees. A quick check on Google Product Search UK, a free price comparison site for products available on the Internet, suggests a price of £164 or more for it.

According to a press release from November 2012 on the BusinessWire website, the product has been on sale since 2007 and has sold 3.5 million units to date. As in the UK, home shopping TV channels seem to be the main format used to sell the product, cutting out retailers and hence enhancing profits.

So, what about patents ? There seem to be quite a few, starting with publications in 1999 and with other improvements or changes following (I think those from 2003 relate to the device). The inventors are two Israelis, Pinchas Shalev and Zion Azar.

This is a list of “World” patent applications by them inventors in the same field. These include Improved electric shaver, with the drawing shown below.

While it seems to be a very successful (if expensive) product, the Internet does have a number of critical comments on it by unhappy customers.

Launch of the Cooperative Patent Classification

Add comment Comments (0)

The much anticipated Cooperative Patent Classification (CPC) is now live on the free Espacenet database as a more detailed version of the International Patent Classification (IPC). It replaces the old ECLA classes in that role.

On that database, asking for “Classification” takes you to the CPC schedules, which can be used in its own search box on the database. The alternative is using the IPC in its own search box.

I have already posted about the concepts behind the CPC.

What is essential now is that anyone running current awareness searches, or who is used to searching a particular subject area, check to see if the classification has changed or if new classes are available. 250000 classes replace the old 160000 ECLA classes, a 56% increase.

Even your searching did not include any of the old ECLA classes, there may be new classes available because of the incorporation of concepts from the US classification – in software, for example. Always have a look, you never know what you may find.

The way the CPC can be used from the schedules is somewhat different from the old ECLA.

There is a single search box in which you enter either keywords or a class, or you can drill down through the A to H sequence. For keywords, a list of possibilities is offered in order of preference. Clicking on the box next to the class moves the class to a search box on the left hand side. This will include “low”, which means that any subordinate classes to the chosen class will also be included in the search (click it to alter to exact class).

You can then either click on “Find patents” to run a search or, if additional fields are to be used such as date spans or keywords or selected patent offices, click on “Copy to search form”. A new search mask appears and the additional requests can be made.

Above the schedules are little icons. These allow extra functions, such as “toggle tree”, where the classes that are subdivided are perhaps show more clearly, and the useful green “CPC” icon. Clicking on this means that any CPC as opposed to IPC material is given in green. If an entire entry describing a class is green it means it is CPC only and is not used by the IPC. Other classes may have additional notes or references in green. To the right of the schedules is a little “S” icon, which converts the selected class to PDF format.

Within the Y classes, for interesting material relevant to climate change (but not used by themselves as they are additional classes to the main ones), the number of subclasses has also been dramatically increased.

Those who want to know if a topic has many entries in the CPC which are not in the IPC will benefit by clicking the green CPC icon plus the toggle tree icon. This can show dramatic differences, as in e-commerce in the G06Q30 area, where most of the entries appear in green and are, I suspect, newly added to the what was ECLA.

The European Union’s new unitary patent

Add comment Comments (0)

The European Parliament passed on the 11 December legislation for a single patent and its unitary court (UPC) for the European Union. The details of the concept are in my previous post.

The European Commission has estimated that the cost of obtaining patent protection for all EU countries is about 36000 Euros, of which 23000 is translation costs. By comparison, they say that the cost of an American patent is 1850 Euros (for private inventors and small companies). The cost of the new patent is estimated to be under 5000 Euros.

A press release by the European Patent Office, which will administer the patent, states “Request for unitary patents may be filed once the legal provisions for both the unitary patent and the UPC have entered into force. The agreement establishing the UPC is expected to be signed on 18 February 2013 and will enter into force once thirteen EU member states have ratified the package, including France, Germany and the UK. The EPO expects to validate the first unitary patent in 2014.”
