Take 200g of fresh snow crab shells, that is, leftovers produced by fresh snow crabs just after aquatic processing in the previous process. After crushing, add 1000g of citric acid solution with a concentration of 5% by mass, soak for 15 hours, filter with gauze, and use tap water or The crab shell is washed with pure water to obtain a decalcified crab shell. The washing residue and the filtrate are combined to obtain a mixture. The mixture is filtered through a plate and frame, and the filter residue is dried to obtain calcium citrate. Add 1000g of 5% citric acid solution and repeat the above steps once to obtain decalcified crab shells; add 1000g of water to the decalcified crab shells, add 2g of flavor enzymes, keep them at 49°C for 3 hours, inactivate the enzymes, filter, and obtain The filtrate is concentrated and spray-dried to obtain crab protein powder. The obtained crab shells are added to 400 g of 10% citric acid solution, soaked for 6 hours, filtered with gauze, and the resulting filter residue is washed and dried to obtain chitin. The obtained filtrate is recovered for subsequent processing. For use, add 55% KOH solution (containing 0.1% potassium acetate) to the obtained chitin, where the mass percentage of chitin and KOH solution is 1:5, at 90°C, keep for 6 hours, filter after cooling, wash, and recover the filtrate and The washing liquid is used again after subsequent treatment. The washed filter residue is irradiated with ultraviolet rays for 12 hours, and 24.2 g of chitosan is obtained after drying.

EP Patent Validation Service



EP Patent Validation Service
Sandeep Mishra
Director at De Science Infoware Pvt Ltd











Traditional route
The conventional route for EP patent validation is for the client to instruct their EP attorneys to execute the validation. The EP attorneys would then instruct a validations provider (like us) or perform the validations themselves using attorney partners in each country who they use based on a reciprocity model, which is usually not cost or quality selective. The EP attorneys would add significant fees for each country.
About our EP Patent Validation service : Why you should go with us.
Benefits of using our EP validation service :
By using a centralised validations provider like us, the client is cutting out one extra layer of cost, which is usually the most significant cost layer. All large patent filers in Europe use a centralised provider like our associate company because of benefits like the following:
Reduced Risk
We with our European team are specialists in European Patent Validation, which means there is a significantly reduced risk of misunderstanding, unexpected costs, or of course the unthinkable risk of accidental loss of a patent due to the complex and constantly changing regulations around Europe.
Reduced Cost
Validation is a significant part of the cost of a European Patent lifecycle, especially if many countries are required. Filing tens of thousands of validations per year, and translating millions of words into every language, means that ours buying power is enormous. We provide user-friendly and extremely efficient processes to our agents and suppliers which further reduce their costs, and all of this means we are able to pass on these savings to our customers.
We expect to able to reduce most client's validations costs by at least 50%
