Compressing Wind Energy

Wind energy, as its name indicates, is highly dependent on the presence of wind. If one wants a windmill to be a permanent source of electricity, some kind storage system buffering energy is needed. One type of storage could be compressed air produced using wind energy generated during wind peaks. The compressed air can then be used to operate a generator when the energy demand is higher than the wind is able to produce. Check the innovative value of this solution, using esp@cenet®.

The e-cigarette: smoke without the fire

This article describes a new type of electronic cigarette that claims to be legal even if used indoors:

"They are already a familiar nocturnal sight on the streets of London - huddles of windswept smokers lighting up outside pubs, clubs and bars. Now one nightclub claims it has solved the problem, allowing smokers to get their fix without having to sneak outside in mid-conversation. Celebrity hangout Chinawhite in Soho is trying out Britain's first ‘e-cig’, a Chinese-made device that mimics the ritual of smoking but is supposedly entirely legal indoors.

“The six-inch white plastic stick uses a battery-powered atomiser to create realistic puffs of ‘smoke,’ while the tip glows red with each inhalation."

Using esp@cenet, try finding patent documents covering this type of cigarette and check how innovative this product is.


Solution

Step one: To find similar patents, identify the most pertinent aspects of the invention -- common technical features that may be found in related patents -- and for each aspect, define a comprehensive set of synonyms. To perform the search, this set of synonyms can be combined as keywords in the patent database.

In this case, the following concepts -- groups of synonyms covering the different aspects of the invention -- can be defined:

- cigarette* smok*

- electr*

The combination “electronic” “cigarette” yields a preliminary list containing some good documents like:

Electronic atomization cigarette, US2007267031

Aerosol electronic cigarette, WO2007131449

Electronic cigarette, US2005016550

Step 2: Use the classification assigned to relevant documents to refine and complete the search.

One of the classification symbols assigned to the above document corresponds to our invention: Simulated smoking devices, e.g. imitation cigarettes with an electrical heating mechanism (A24F47/00B2E)

Using this classification as a search criteria yields this list containing 564 documents. This result shows that this field is far from new and that a lot of IPRs already exist. In addition, it should be noted that many patents that appeared in the keyword search were Chinese. Only titles and complete documents were available, making a deeper prior art analysis a real language challenge.
