Description
Technical field
The invention belongs to value forecasting processing method, be specifically related to the appraisal procedure of patent value.
Background technology
Patent is as important intangible asset, and the assessment of its transaction value or price is the basis of patent Transformation Application.Patent valve estimating is for promoting the transformation of scientific and technological achievements, and the importance promoting national science and technology innovation is self-evident.
Buddhist nun gram Bert loti is the complexity disclosing intellectual property evaluation of system in " appraisal procedure of intellectual property " (" China's assets assessment " 1997-1:22-27).And for three kinds of main method commonly used in practice: cost-or-market method, Market valuation method, income present value method have contrasted.Wherein cost-or-market method can be subdivided into again historical cost and the replacement cost.The common ground of both approaches is to sum up the cost expended in intellectual property initiative process to be assessed.Being distinctive in that historical cost is the cost of actual expenses in exploitation, the replacement cost is again to purchase intellectual property or create the required cost expended of same intellectual property.And market method also can be subdivided into comparable Market valuation method and comparable use rate method.Comparable Market valuation method, is to determine the value of intellectual property to be assessed with reference to the price of comparable intellectual property in the last transaction；Comparable use rate method, is to determine the value of intellectual property to be assessed with reference to agreed comparable use rate in the last transaction.Present worth of income is by collecting the checking information material about operation, financial situation, calculate index relevant to relative analysis and variation tendency thereof, it was predicted that assets expected future increases income newly, it is determined that discount rate or capital rate, newly-increased for expection income is discounted, it is determined that evaluated assets value.Income present value method is made up of two parts: the identification of the cash flow that the first is produced by intellectual property, differentiation and quantization；It two is the capitalization of cash flow.
Except above-mentioned three kinds of conventional patent value assessment method, the art also has many exploration and trial.In October, 2012, patent administration department of State Intellectual Property Office, China's technology business are organized to write and published " patent value analysis indexes system workbook ", weighed the value of patent by legal value degree, technological value degree and economic worth degree three aspect, each action value comprises again many two-level index.But this index system is excessively complicated, some index is difficult to obtain, and therefore lacks direct directive significance for the practice of value assessment.Jiangsu University Wang Xiu is red, Yuan Yan is in CN201310694516.6 (a kind of patent value assessment method), the problem of objectivity and exploitativeness in order to solve profit value assessment, Derwent database D WPI based on internal authority carries out related patent data, is weighted assessing from company strength angle and technological competitiveness angle to patent value.Wuhan University Peng Zhi bravely waits in CN201310036016.3 (a kind of patent value assessment method based on value delivery), utilizes the citation relations between patent to judge the relative worth of patent.Mould in CN201410264351.3 (computational methods of patent value degree and system), write the factors such as quality assess the action value of patent by analysis infringement necessity, technological value, term of a patent, the infringement easily property sentenced, ownership stability, patent documentation.But above-mentioned three inventions are only capable of the action value of assessment patent, it is impossible to the market value of patent is provided comments.
Zhou Lin discusses basic conception and the theoretical foundation of intellectual property evaluation in " trying to make a comment basic conception and the theoretical foundation of intellectual property evaluation " (" Central-South China Institute of Politics and Law's journal " 1996-6:51-56), point out that obligee more pays close attention to current market value or the price of intellectual property, and often have ignored this and assess the committed step that this value is produced.Point out the difference that intellectual property evaluation exists with intangible asset technology evaluation simultaneously.Think the multiple intellectual property evaluation formula introduced in domestic and international economics treatise, seldom use in practice.
Dong Xiaofeng, Li little Ying points out in " investigation and analysis to Intellectual Property Right in China appraisal procedure " (" economic problems exploration " 2005-5:119-125), and the current intellectual property evaluation method of China generally mainly has: cost-or-market method, Market valuation method, income present value method.But due to the characteristic of intellectual property itself, especially having the factor that many impacts are worth in the evaluation process of intellectual property, subjective randomness is relatively big, and the scientific rationality of traditional intellectual property evaluation waits further research.
According to the theory of modern economics, the market price of commodity is subject to the impact of the demand-supply relation completely, with the cost of commodity onrelevant.Therefore the transaction for patent that is worth adopting cost-or-market method assessment patent there is no too many directive significance.And the patent that most of patent to be transacted especially scientific research institutions produce does not come into operation, adopt income approach that it is carried out the conclusion subjectivity randomness that value assessment obtains bigger.As most of commodity, market is only the final factor finding and determining patent value, and patent valve estimating have to use market method just accurate, and this is unquestionable.It is identical for not having two pieces patent, it is identical for so there is no the transaction of two pieces patent, as in " intellectual property value assessment, exploitation and tort compensation " (ISBN:978 0 471 68,323 0) book, pointed by author: " because never a real trade mates completely with virtual trading; appraiser is faced with all the time about the reasonable judgement to comparability, and be judged as that some of real trade key element are regulateed whether guaranteed by raising similarity." and: " for the market method of patent and technology, in all scenario that this chapter is discussed, have a lot of praiseworthy aspect.Regrettably, patent and technology seldom can be used by the data required for the method for implementation market.Essential element required for carrying out market method includes, the transaction between the transaction of similar property, each independent community, etc..”
In the price-setting process of financial product, often can adopt market survey method, be confirmed the price of assets to be transacted by the mode inquired the price.Such as, inquiry link before initial public offering, sends inquiry notice to professional institution, understands quantity and price that potential buyer's wish is bought, collects potential buyer for, after notice institute feedack of inquiring the price, formulating issue price.But for patent transaction, if inquired the price before the trade, then can expose Transaction Information in advance, it is possible to bring unforeseen risk to transaction.Inquiry method is not yet used to assess transaction value at present in patent transaction.
Summary of the invention
For solving the problems referred to above, inventor is in addition perfect to the market method of patent valve estimating, it is proposed to the new method of the valency that reflects for patent, for predicting the guiding price of patent transaction, also referred to as market benchmark valency.
Set up the full dimension index system F affecting patent value, it is made up of objective indicator B and subjective index C two parts, objective indicator B can be by computer checking and calculated data, and subjective index C is the index item obtaining scoring conclusion only by manual analysis.Building patent information database D with the granted patent data of open announcement and documentation & info, the information subsequently patent information database D comprised carries out value added.Each item data including the objective indicator B and subjective index C of the index system F corresponding to each patent in successively supplementary patent information database D；Extensively collect the data of the price amount of money P of patent, using the patent that can collect patent price amount of money P in patent information database D as DH, it is impossible to collected the patent of patent price amount of money P as DE.
Draw the retrieval treating mirror valency patent X correspondence index system F indices and analyze result FX.For a patent of invention X treating mirror valency, method initially with mathematical analysis, search out from patent information database D and treat, with this part, the patent of invention patent DJ as a comparison that more than one piece the most close for mirror valency patent X has authorized, wherein have the patent of patent price amount of money P in patent information database D to be labeled as DHJn (n is positive integer, represent the sequence number of every contrast patent DHJ respectively), it is labeled as DEJk (k is positive integer, represents the sequence number of every contrast patent DEJ respectively) without the patent of patent price amount of money P.Subsequently according to the price of market exchange PHJn or virtual concluded price PEJk of these contrasts patent DJ, calculate the transaction guide price treating mirror valency patent X.
In order to obtain the virtual concluded price of contrast patent DEJk, use for reference " inquiry " pattern of financial transaction, set up " market wish concluded price " and investigate system.Extensively attracting patent potential buyer to participate in cooperation, every contrast patent DEJk should be provided wish concluded price by multidigit potential buyer.Potential buyer can also be asked to provide wish concluded price for DHJn, by each potential buyer of comparison for the difference between the patent price amount of money P of the DHJn wish concluded price provided and DHJn, judge that (m is positive integer for the assessment bias index β m of each potential buyer, represent the sequence number of potential buyer), and utilize β m to be modified for each the DEJk wish concluded price provided for this potential buyer, then calculate the virtual concluded price numeral PEJk of DEJk.
It is an advantage of the current invention that:
1. the problem for solving patent transaction data deficiency, comprehensive patent transaction price data, authorization price data, the tort compensation amount of money and the patent valve estimating value data of using, and with treat the data such as the market wish concluded price reference as value assessment of the mirror similar patent of valency patent.It is greatly expanded the Market Comparison Approach scope of application in patent mirror valency field.
2. when screening and until the contrast patent that mirror valency patent is similar, index item is divided into objective indicator and subjective index two class, and adopt full dimensional comparison the mathematic calculation in conjunction with big data analysis, avoid the deviation in the past relying on artificial preparing price index system to bring, overcome the random excessive shortcoming of conventional value assessment subjectivity.
3. the result of valency of reflecting each time and the feedback opinion of client are input in patent data warehouse D, as the reference of the valency that reflect from now on.The time that native system runs is more long, and in patent data warehouse D, the price data of accumulation is more many, and mirror valency conclusion is also more accurate.
4. set up index system F, F to be made up of objective indicator B and subjective index C two parts.Objective indicator can use area of computer aided computing to obtain a result, and is greatly saved the human cost of mirror valency, and improves the efficiency of mirror valency.
5. comparison aggregation process respectively be can carry out for the different types of price data of separate sources, it is also possible to the type not distinguishing price data carries out aggregation process, motility and accuracy that data process taken into account.

3. pair information that patent information database D comprises carries out value added.Each item data including the objective indicator B and subjective index C of the index system F corresponding to each patent in successively supplementary patent information database D；Extensively collect the data of the price amount of money P of patent, using the patent that can collect patent price amount of money P in patent information database D as DH, it is impossible to collected the patent of patent price amount of money P as DE.For having the patent DH of the price amount of money except the record price amount of money, in addition it is also necessary to the information of registration confirmed price time T and price type Pi.Price amount of money P can be the data of dealing money, the authorization amount of money, the tort compensation amount of money and the patent valve estimating amount of money.Confirm that price time T refers to this patent and realizes the date information of transaction, mandate, reparation, assessment.I in price type Pi is positive integer, for instance: estimated value or tort compensation amount of money P1 that patent concluded price or patent trade both sides all approve represent；The estimated value P2 of license exercise price or buyer's accreditation represents；Estimated value or the virtual concluded price P3 of seller's accreditation represent.
4. draw the retrieval treating mirror valency patent X correspondence index system F indices and analyze result FX.The method of indices analysis and judgement is as in the table below.Wherein B01～B21 is by retrieving disclosed patent database and bibliographic data base and calculating obtains, and C01～C09 is by manual analysis and marks.
5. according to analysis result FX obtained above, set search condition, retrieve from patent information database D, to filter out indices and the FX contrast patent being closer to.The contrast patent retrieved, if there being patent price amount of money P in patent information database D, is then designated as DHJn (n is positive integer, represents the sequence number of this part contrast patent)；If there not being price amount of money P, then it is designated as DEJk.Preferably, preferential retrieval has the patent DH of price amount of money P.Search condition can adopt index to sort one by one, screens out a part of patent differed greatly with FX after every minor sort.Such as with the B01 index value of FX for benchmark, the B01 numerical value of DH patents all in patent information database D is compared with the B01 numerical value row of FX, screen out the patent more than 50% of the B01 index value difference with FX；The patent not screened out, based on the B02 index value of FX, screens out the patent more than 50% of the B02 difference with FX；... until all indexs all complete sequence and screen out, the residue patent not screened out contrasts patent DHJn exactly.May be used without index screening method is search condition.Preferably, service index screening method, concrete grammar is: the range of search that in setting target system F, each index there are differences with this index value of FX, for instance be set to ± 20% for B01, be set to ± 24 months for B04, etc.；According to set range of search, the contrast patent DJ meeting above-mentioned search condition is retrieved from patent information database D, wherein have the patent of patent price amount of money P to be labeled as DHJn (n is positive integer, represent the sequence number of every contrast patent DHJ respectively), it is labeled as DEJk (k is positive integer, represents the sequence number of every contrast patent DEJ respectively) without the patent of patent price amount of money P.If the contrast patent DHJ quantity retrieved is too many, then the range of search tightening up indices filters out immediate contrast patent DHJ.If the contrast patent DHJ quantity retrieved is very little, it is possible to take the mode relaxing range of search again to retrieve, it is also possible to the method for following 6th step, make up the deficiency of DHJ by the quantity of DEJ.
6. by mirror valency personnel by the contrast patent numbers needed for micro-judgment mirror valency.Preferably, adopt and contrast the patent basis as mirror valency no less than 10.If the contrast patent DHJ quantity retrieved from patent information database D is less than the quantity needed for mirror valency, or cannot find at all and treat the mirror valency patent X contrast patent DHJ being closer to, then can according to the method for above-mentioned steps 4 and step 5, first from patent information database D, retrieve the immediate more than one piece patent of index B01～B21 and FX, C01～C09 index of patent is retrieved subsequently according to these, screen out the patent wherein differed greatly with FX, remaining more than one piece patent composition contrast patent DEJk.
7. use for reference " inquiry " pattern of financial transaction, set up " market wish concluded price " and investigate system.Patent potential buyer is extensively attracted to participate in cooperation, every contrast patent DHJn and DEJk should be provided wish concluded price by multidigit potential buyer, investigation m position potential buyer is being subject to wish concluded price mPHn and the mPEk (n, k are positive integer, represent the sequence number of this part contrast patent) of investigation timing node for contrast patent DHJn and the DEJk provided by above-mentioned steps.Wish concluded price DHJn provided for m position potential buyer is recorded as mPHn；Wish concluded price DEJk provided for m position potential buyer is designated as mPEk (m is positive integer, represents the sequence number of potential buyer).The information of potential buyer can be obtained by market survey.Preferably, it is possible to found by patent searching information D and had assigned patents recently or be licensed the unit of patent.
8. calculate the m position potential buyer assessment bias index β m for the contrast patent DHJ with price data.Obtain the method for β m can be by m position patent potential buyer for the DEJk wish concluded price mPEk provided and all potential buyers for the meansigma methods of the DEJk wish concluded price provided carry out compared with obtain.Preferably, when having the quantity of contrast patent DHJ of patent price amount of money P be more than or equal to 1, following method can be adopted to obtain the assessment bias index β m of m position potential buyer: contrast patent DHJ above-mentioned steps 5 obtained, from patent information database D, inquiry obtains the price data PHJn (n is positive integer, represents the sequence number of this part contrast patent) of each contrast patent DHJn.First PHJn and mPHn is contrasted, calculate the assessment bias index β m of reflection m position potential buyer；With β m, the wish concluded price mPEk that DEJk is provided by m position potential buyer is modified obtaining m position potential buyer to the revised wish concluded price mPEJk of DEJk subsequently；Contrast patent DEJk finally, for kth part, the revised wish concluded price mPEJk (now k immobilizes) of multiple potential buyers is averaged and obtains the market wish concluded price numeral PEJk of DEJk.The computing formula of foregoing is as follows successively:
β m=1 ÷ n × ∑ [1-(mPHn-PHJn)/PHJn] (wherein m is constant, n 1)
MPEJk=β m × mPEk (wherein k is constant, m 1)
PEJk=1 ÷ m × ∑ mPEJk (wherein k is constant, m 1)
9. the data of couple PHJn and PEJk carry out Mathematical treatment, it is judged that treat the transaction guiding price of mirror valency patent X, in this, as mirror valency conclusion.Mathematic(al) mean method can be adopted to may be used without linear regression method.Preferably, adopt mathematic(al) mean method, concrete grammar is: respectively according to P1, P2 and P3 dissimilar, calculate its meansigma methods.After the price number of all P1 classes is added, divided by the quantity of P1 price patent；After the price number of all P2 classes is added, divided by the quantity of P2 price patent；After the price number of all P3 classes is added, divided by the quantity of P3 price patent.Divided by 3 after the meansigma methods of P1, P2 and P3 being added subsequently, obtain treating the transaction guide price of mirror valency patent X.If the price data lacking P1 class or P2 class in the data of PHJn has no effect on final mirror valency conclusion.Especially, also need to according to DHJn that (n is positive integer when adopting linear regression method, represent this part contrast patent sequence number) closing time, the exchange rate of Reference Transactions spot, interest rate, and term of a patent the factor such as loses, according to the passing method of financial process, the price amount of money PHJn of past time point is converted the price amount of money for current time point.
It should be noted that the present invention is best suited for the mirror valency of patent of invention.For utility model and appearance patent, it is possible to first utility model and appearance patent are carried out patent right assessment, if right consolidates, it is possible to use this method mirror valency.
Embodiment 1, it is considered to the difference of different price type, and the while of with the pricing information of the contrast patent DHJ of price data
