IP protection


1 Please provide a short description of the state-of-the-art and/or current trends in the field? How does the result fit into it?
The proposed springless valve system for internal combustion engines substitutes the standard valve system with springs, thus leading to noticeable decrease of rotation resistance of the engine and therefore helping lowering fuel consumption and harmful emissions of conventional engine. The system is manufactured with 30% less raw materials compared to the conventional one.  Amongst the main advantages of this springless valve system are also the great wearing out resistance, enhanced by the substitution of the friction bearings with ball ones, simplified design and implementation without changes in the mechanism of the nowadays automobile production lines. There are similar systems manufactured and patented mainly in the USA. However none of the comparable systems has the abilities for direct incorporation in a conventional engine plus implementation directly in the automotive production lines.


2 What is the problem/need/knowledge gap that the research result is responding to?  How was it addressed before?
The springless valve system helps facing one of the greatest and most important needs in the modern times – to face the challenge of the constant and ongoing environmental pollution. All advantages of the system have direct impact on this goal – lowered fuel consumption up to 5-8%, lowered raw materials costs for production by 30%, simplified production, lowered engine harmful emissions, lowered engine/valves wearing out and increased life cycle of the engine. Last, but not least, is the prolonged service intervals and simplified maintenance, due to the superior results, shown in turnover resistance tests.


3 What is the potential for further research?
Further research to be focused on developing different types of springless valve systems, which could be suitable for all type and brands of engines, bearing in mind the specifications and diversities of the different leading internal combustion engines manufacturers. Matching the specific requirements of the leading automotive suppliers could significantly boost the demands and broaden the future markets for the product. The spring-less system could also greatly contribute reducing the direct production costs and increasing the availability and profitability of the automobile production.







4 What is the proposed method of IPR-protection? (patent, license, trademark etc.)
The internal research, held with the WIPO registration system, revealed worldwide granted by USPTO patents for analogical or similar valve systems. Therefore the proposed IP protection could be as industrial design or as utility model, based on the differences in the construction, compared to the rivals. Besides this, the researcher could apply for granting an international trade mark. Due to the large number of European internal combustion engines manufacturer the industrial design/utility model and trade mark protection could be extended EC/Europe for the first stage.



5 What are the steps that need to be taken in order to secure the IPR-protection? What is the cost of IPR-protection?
In order to apply for IP protection in the means of utility model the company must prepare a description, clearly stating the differences and strong sides of its technical decision, compared to those of the competitors. It is advisable also to be filled an application for trade mark protection in the Bulgarian Patent Office. In case of positive development the company could receive an EC IP registration, which could be extended into worldwide one at the next stage.  The approximate costs for the first stage IP protection for the European union are 7000 EUR.


6 What is you overall assessment of the scientific maturity of the research result?
Although there are similar technical decisions the proposed prototype proves better results, especially in the cost reduction (over 30%). This multiplied by the significant increase in the exploitation period of the engine and the lowered fuel consumption, makes the product suitable for mass production. The result of the scientific research can be implemented at mass scale production, thus leading to direct benefits of lowered rotating resistance, prolonged service intervals, prolonged service life, cut off in the fuel consumption and decrease of the raw materials, used for manufacturing of the system.
