Abstract
Description
本發明是有關於一種風險評估機制,且特別是有關於一種評估交易對象的方法。The present invention relates to a risk assessment mechanism, and in particular to a method for assessing transaction objects.
有鑑於過去評估交易對象時,僅以新聞查找、官方網站等單一面向去評估該公司的風險,當交易對象為一間新註冊的公司,沒有歷史資訊與背景,公司要判斷該交易對象是否為可信賴之合作夥伴,有實務上的困難,許多企業目前各大公司與其他公司之間的往來關係,多半存在著參考白名單或黑名單的制度,對於已列入黑名單之交易對象,若再以用設立新公司或另找相關聯之企業,以迂迴方式與本公司尋求合作機會,以現存徵信手段方式恐難察覺。In view of the fact that when evaluating the transaction object in the past, the company's risk was only evaluated from a single aspect such as news search and official website. When the transaction object is a newly registered company without historical information and background, the company should judge whether the transaction object is a Reliable partners have practical difficulties. Many companies currently have a relationship between major companies and other companies, and most of them have a system of referring to a whitelist or a blacklist. It may be difficult to detect with the existing credit investigation methods by setting up a new company or finding another related company to seek cooperation opportunities with the company in a roundabout way.
有鑑於此,本發明提供一種評估交易對象的方法,其可用於解決上述技術問題。In view of this, the present invention provides a method for evaluating a transaction object, which can be used to solve the above-mentioned technical problems.
本發明提供一種評估交易對象的方法,包括:蒐集多個交易對象個別的一評分及多個關聯屬性值,其中前述交易對象包括一第一交易對象及多個第二交易對象;基於前述交易對象個別的前述關聯屬性值建立一關聯矩陣,其中關聯矩陣記錄各交易對象與前述關聯屬性值之間的一關聯係數;基於關聯矩陣找出第一交易對象與前述第二交易對象之間的多個走訪路徑,其中各走訪路徑包括串接的多個節點,且前述節點中的一起始節點對應於第一交易對象;基於各第二交易對象的評分估計各走訪路徑的一路徑成本;基於各走訪路徑的路徑成本估計第一交易對象的一交易風險分數。The present invention provides a method for evaluating transaction objects, comprising: collecting a score and a plurality of associated attribute values of a plurality of transaction objects, wherein the transaction objects include a first transaction object and a plurality of second transaction objects; based on the transaction objects The individual aforementioned associated attribute values establish an association matrix, wherein the association matrix records a correlation coefficient between each transaction object and the aforementioned associated attribute value; based on the association matrix, find out a plurality of the relationship between the first transaction object and the aforementioned second transaction object. A visit path, wherein each visit path includes a plurality of nodes connected in series, and an initial node in the aforementioned nodes corresponds to the first transaction object; a path cost of each visit path is estimated based on the score of each second transaction object; based on each visit The path cost of the path estimates a transaction risk score for the first transaction object.
為讓本發明的上述特徵和優點能更明顯易懂,下文特舉實施例,並配合所附圖式作詳細說明如下。In order to make the above-mentioned features and advantages of the present invention more obvious and easy to understand, the following embodiments are given and described in detail with the accompanying drawings as follows.
概略而言,本發明希望納入過去與公司交易之合作經驗,更具體將交易對象之間的關係用正規化的方式定義風險等級,提供一個更有效與多面向的分析結果,致力發展一個可適用所有交易對象的風險等級評估,以下將作進一步說明。Roughly speaking, the present invention hopes to incorporate the experience of cooperation with companies in the past, and more specifically, to define the risk level in a formalized way for the relationship between transaction objects, to provide a more effective and multi-faceted analysis result, and to develop an applicable The risk level assessment of all transaction objects will be further explained below.
為便於理解本發明的概念,以下另輔以一實際情境作說明。在本發明的情境中,假設交易對象02與實現本發明方法的公司A之間有業務上往來,施工品質不佳且與供應商之間有財務糾紛,因此將交易對象02核予較低評分。由於公司A傾向避免與具高風險之交易對象合作,故交易對象02轉而成立新公司B參與公司A的標案,而此新公司B為交易對象05。交易對象05為新進市場之交易對象,以一般核定標準,可取得中等的評等分數,但管理階層人員卻與交易對象02相關,意即交易對象05未來有機率成為高風險之交易對象,致使本公司蒙受損失。上述情境在實務上經常發生,而藉由本發明方法可得到可供參考之風險評等分數,從而達到為企業達到把關的效果。In order to facilitate the understanding of the concept of the present invention, an actual situation is supplemented below for description. In the context of the present invention, it is assumed that the
請參照圖1,其是依據本發明之一實施例繪示的評估交易對象的方法流程圖。在不同的實施例中,本發明的方法可由特定的電腦伺服器、工作站、智慧型裝置執行,以基於公司A人員的操作而實現圖1中的各步驟,詳細說明如下。Please refer to FIG. 1 , which is a flowchart of a method for evaluating a transaction object according to an embodiment of the present invention. In different embodiments, the method of the present invention may be executed by a specific computer server, workstation, or smart device to implement the steps in FIG. 1 based on the operations of Company A personnel, which are described in detail below.
首先,在步驟S110中,可蒐集多個交易對象個別的評分及多個關聯屬性值,其中前述交易對象包括第一交易對象及多個第二交易對象。在本發明的實施例中,所述第一交易對象例如是使用者所輸入的待評估的交易對象(即,交易對象05),而第二交易對象例如是可用於輔助評估第一交易對象的其他交易對象(例如交易對象02)。First, in step S110, individual scores and multiple associated attribute values of a plurality of transaction objects may be collected, wherein the foregoing transaction objects include a first transaction object and a plurality of second transaction objects. In the embodiment of the present invention, the first transaction object is, for example, a transaction object to be evaluated (ie, transaction object 05 ) input by the user, and the second transaction object is, for example, available to assist in evaluating the first transaction object Other transaction objects (eg transaction object 02).
在一實施例中,假設本發明共考慮交易對象00、01、02、03、04、05以及關聯屬性值a、b、c、d。在不同的實施例中,關聯屬性值a~d可具有不同的實施態樣,例如地理區域、董監事、聯絡電話、代表人、持股比例等,但不限於此。基此,本發明例如可藉由存取/搜尋資料庫中的歷史資料、公開資訊、財政部登記資料、新聞或爬網等,整合各管道資源後將各交易對象00~05與對應的關聯屬性值a~d匯整為如圖2之關聯表。In one embodiment, it is assumed that the present invention considers
請參照圖2,其是依據本發明之一實施例繪示各交易對象的關聯表。由圖2可看出交易對象00、01、04皆具有關聯屬性值d(例如皆位於某個特定縣市);交易對象04與02皆具有關聯屬性值a(例如具有一或多個相同的董監事);交易對象02、05皆具有關聯屬性值c(例如具有相同的聯絡電話);僅有交易對象03具有關聯屬性值b。Please refer to FIG. 2 , which is an association table showing each transaction object according to an embodiment of the present invention. It can be seen from Figure 2 that
此外,各交易對象00~05的評分例如是先前已透過本發明的方法對各交易對象00~05估計過的交易風險分數,但可不限於此。在一實施例中,各交易對象00~05的評分可如下表1所例示。此外,在本發明的情境中,由於交易對象05對應於新公司B,故暫無相關的評分。
之後,在步驟S120中,可基於交易對象00~05個別的關聯屬性值建立關聯矩陣。在一實施例中,上述關聯矩陣(以R[X,Y]表示)的維度例如是MxN,其中M為交易對象00~05的數量(即,6),而N為關聯屬性值a~d的數量(即,4)。並且,若交易對象00~05中的第i個交易對象具有關聯屬性值a~d中的第j個關聯屬性值,則本發明可將關聯矩陣中第i列第j行的元素設定為一關聯係數(例如,1)。Afterwards, in step S120, an association matrix may be established based on the individual associated attribute values of transaction objects 00-05. In one embodiment, the dimension of the above-mentioned correlation matrix (represented by R[X, Y]) is, for example, MxN, where M is the number of transaction objects 00-05 (ie, 6), and N is the correlation attribute value a-d number (ie, 4). Moreover, if the i-th transaction object in the transaction objects 00-05 has the j-th associated attribute value in the associated attribute values a-d, the present invention can set the element of the i-th column and the j-th row in the association matrix as a Correlation coefficient (for example, 1).
請參照圖3,其是依據本發明之一實施例繪示的關聯矩陣示意圖。在本實施例中,交易對象00~05的集合可表示為X={X00
,X01
,X02
,X03
,X04
,X06
},而關聯屬性值a~d的集合可表示為Y={Ya
,Yb
,Yc
,Yd
},但可不限於此。Please refer to FIG. 3 , which is a schematic diagram of an association matrix according to an embodiment of the present invention. In this embodiment, the set of
依據圖2可知,由於交易對象00(即,第1個交易對象)具有關聯屬性值d(即,第4個關聯屬性值),故圖3中關聯矩陣300的第1列第4行的元素(可表示為R[X00
,Yd
])可相應地設定為1。相似地,由於交易對象04(即,第5個交易對象)亦具有關聯屬性值d,故圖3中關聯矩陣300的第5列第4行的元素(即,R[X04
,Yd
])可相應地設定為1。基於以上教示,本領域具通常知識者應可理解關聯矩陣300中其他元素的涵義,於此不另贅述。According to Fig. 2, since the transaction object 00 (ie, the first transaction object) has an associated attribute value d (ie, the fourth associated attribute value), the elements in the first column and the fourth row of the
接著,在步驟S130中,可基於關聯矩陣300找出第一交易對象(即,交易對象05)與第二交易對象(即,交易對象00~04)之間的多個走訪路徑(或可理解為關聯路徑)。Next, in step S130 , based on the
具體而言,由圖3的R[X06
,Yc
]=1、R[X02
,Yc
]=1可得知新加入的交易對象05與交易對象02透過關聯屬性值c產生直接關聯,意即指交易對象02及05之間具有相同的關聯屬性值c,且關聯跳躍數為1,表示兩者的關聯性非常高。同理,由圖3還可看出,交易對象04透過關聯屬性值a與交易對象02產生關聯,而交易對象02又與交易對象06藉由關聯屬性值c產生關聯,表示交易對象04與交易對象06透過交易對象02產生關聯,屬於間接關聯,跳躍數為2。間接關聯的跳躍數越多,代表兩家交易對象之間的關聯越薄弱,但仍然是有相關的。Specifically, from R[X 06 , Y c ]=1 and R[X 02 , Y c ]=1 in FIG. 3 , it can be known that the newly added
在一實施例中,在產生關聯矩陣300的過程中,同時也形成了第一交易對象(即,交易對象05)與第二交易對象(即,交易對象00~04)之間的走訪路徑。In one embodiment, in the process of generating the
請參照圖4,其是依據本發明之一實施例繪示的走訪路徑示意圖。在本實施例中,依據關聯矩陣300,第一交易對象(即,交易對象05)與第二交易對象(即,交易對象00~04)之間共可形成走訪路徑410、420。Please refer to FIG. 4 , which is a schematic diagram of a visiting route according to an embodiment of the present invention. In this embodiment, according to the
概略而言,對於走訪路徑410、420中的一特定走訪路徑而言,其可包括串接的T個特定節點,各特定節點對應於交易對象00~05之一,且前述特定節點中的第1個特定節點對應於第一交易對象(即,交易對象05)。並且,前述特定節點中的第k個特定節點與第k-1個特定節點皆具有前述關聯屬性值中的第一關聯屬性值,其中k為大於1小於T的整數;前述特定節點中的第k+1個特定節點與第k個特定節點皆具有前述關聯屬性值中的第二關聯屬性值,且第一關聯屬性值不同於第二關聯屬性值。Roughly speaking, for a specific visit path in the
以走訪路徑410為例,其中的第1個特定節點係對應於交易對象05。由圖3可看出,由於交易對象02與交易對象05皆具有關聯屬性值c,故走訪路徑410中的第2個特定節點係對應於交易對象02。另外,由於交易對象04與交易對象02皆具有關聯屬性值a,故走訪路徑410中的第3個特定節點係對應於交易對象04。同理,由於交易對象00與交易對象04皆具有關聯屬性值d,故走訪路徑410中的第4個特定節點係對應於交易對象00。Taking the
此外,由走訪路徑410可看出,第k個特定節點與第1個特定節點之間存在k-1個跳躍(hop)。例如,第2個(k=2)特定節點(對應於交易對象02)與第1個特定節點之間存在1個跳躍;第3個(k=3)特定節點(對應於交易對象04)與第1個特定節點之間存在2個跳躍;第4個(k=4)特定節點(對應於交易對象00)與第1個特定節點之間存在3個跳躍。In addition, it can be seen from the
再以走訪路徑420為例,其中的第1個特定節點係對應於交易對象05。由圖3可看出,由於交易對象02與交易對象05皆具有關聯屬性值c,故走訪路徑420中的第2個特定節點係對應於交易對象02。另外,由於交易對象04與交易對象02皆具有關聯屬性值a,故走訪路徑420中的第3個特定節點係對應於交易對象04。同理,由於交易對象01與交易對象04皆具有關聯屬性值b,故走訪路徑420中的第4個特定節點係對應於交易對象01。Taking the
此外,由走訪路徑420亦可看出,第2個(k=2)特定節點(對應於交易對象02)與第1個特定節點之間存在1個跳躍;第3個(k=3)特定節點(對應於交易對象04)與第1個特定節點之間存在2個跳躍;第4個(k=4)特定節點(對應於交易對象01)與第1個特定節點之間存在3個跳躍。In addition, it can also be seen from the
在取得走訪路徑410、420之後,在步驟S140中,可基於各第二交易對象的評分估計各走訪路徑410、420的路徑成本。After the visiting
在一實施例中,對於走訪路徑410、420中的特定走訪路徑而言,本發明可估計特定走訪路徑中的各特定節點的權重分數,並據以計算各特定節點的權重分數的分數平均值,以作為特定走訪路徑的路徑成本。In one embodiment, for a specific visit path in the
概略而言,對於特定走訪路徑中的第k個特定節點而言,本發明可取得對應於所述k-1個跳躍的一權重值,其中權重值負相關於所述k-1個跳躍(即,特定節點的跳躍數越多,權重值越低)。之後,本發明可取得所述第k個特定節點對應的第二交易對象的評分,並依據權重值將其修正為所述第k個特定節點的權重分數。接著,本發明可取得各所述第k個特定節點的權重分數的分數平均值,以作為特定走訪路徑的路徑成本。Roughly speaking, for the kth specific node in a specific visit path, the present invention can obtain a weight value corresponding to the k-1 hops, wherein the weight value is negatively related to the k-1 hops ( That is, the more hops a particular node has, the lower the weight value). Afterwards, the present invention can obtain the score of the second transaction object corresponding to the kth specific node, and modify it into the weight score of the kth specific node according to the weight value. Then, the present invention can obtain the average score of the weight scores of each of the k-th specific nodes as the path cost of the specific visiting path.
以走訪路徑410為例,對於其中的第2個特定節點(對應於交易對象02),本發明可取得對應於1個跳躍的權重值(例如1),之後,本發明可取得第2個特定節點對應的第二交易對象(即,交易對象02)的評分(即,20),並依據上述權重值(即,1)將其修正為第2個特定節點的權重分數。在一實施例中,第2個特定節點的權重分數例如是20(即,20x1)。Taking the
對於走訪路徑410中的第3個特定節點(對應於交易對象04),本發明可取得對應於2個跳躍的權重值(例如0.9),之後,本發明可取得第3個特定節點對應的第二交易對象(即,交易對象04)的評分(即,70),並依據上述權重值(即,0.9)將其修正為第3個特定節點的權重分數。在一實施例中,第3個特定節點的權重分數例如是63(即,70x0.9)。For the third specific node (corresponding to the transaction object 04) in the visiting
對於走訪路徑410中的第4個特定節點(對應於交易對象00),本發明可取得對應於3個跳躍的權重值(例如0.8),之後,本發明可取得第4個特定節點對應的第二交易對象(即,交易對象00)的評分(即,60),並依據上述權重值(即,0.8)將其修正為第4個特定節點的權重分數。在一實施例中,第4個特定節點的權重分數例如是48(即,60x0.8)。For the 4th specific node (corresponding to the transaction object 00) in the visiting
之後,本發明可取得走訪路徑410中各特定節點的權重分數的分數平均值,以作為走訪路徑410的路徑成本。在一實施例中,走訪路徑410的路徑成本例如是43.7(即,(20+63+48)/3)。Afterwards, the present invention can obtain the average score of the weight scores of each specific node in the visited
再以走訪路徑420為例,對於其中的第2個特定節點(對應於交易對象02),本發明可取得對應於1個跳躍的權重值(例如1),之後,本發明可取得第2個特定節點對應的第二交易對象(即,交易對象02)的評分(即,20),並依據上述權重值(即,1)將其修正為第2個特定節點的權重分數。在一實施例中,第2個特定節點的權重分數例如是20(即,20x1)。Taking the
對於走訪路徑420中的第3個特定節點(對應於交易對象04),本發明可取得對應於2個跳躍的權重值(例如0.9),之後,本發明可取得第3個特定節點對應的第二交易對象(即,交易對象04)的評分(即,70),並依據上述權重值(即,0.9)將其修正為第3個特定節點的權重分數。在一實施例中,第3個特定節點的權重分數例如是63(即,70x0.9)。For the third specific node (corresponding to the transaction object 04) in the visiting
對於走訪路徑420中的第4個特定節點(對應於交易對象01),本發明可取得對應於3個跳躍的權重值(例如0.8),之後,本發明可取得第4個特定節點對應的第二交易對象(即,交易對象01)的評分(即,40),並依據上述權重值(即,0.8)將其修正為第4個特定節點的權重分數。在一實施例中,第4個特定節點的權重分數例如是32(即,40x0.8)。For the 4th specific node (corresponding to the transaction object 01) in the visiting
之後,本發明可取得走訪路徑420中各特定節點的權重分數的分數平均值,以作為走訪路徑420的路徑成本。在一實施例中,走訪路徑420的路徑成本例如是38.3(即,(20+63+32)/3)。Afterwards, the present invention can obtain the average score of the weight scores of each specific node in the visiting
在取得各走訪路徑410、420的路徑成本(即,43.7及38.3)之後,在步驟S150中,可基於各走訪路徑410、420的路徑成本估計第一交易對象(即,交易對象05)的交易風險分數。在一實施例中,本發明可取得各走訪路徑410、420的路徑成本的成本平均值,以作為第一交易對象(即,交易對象05)的交易風險分數,例如41(即,(43.7+38.3)/2)。在此情況下,表1可更新為如下表2所例示之態樣。
在取得交易對象05的交易風險分數之後,其可提供給公司A內部人員作為參考,成為是否與交易對象05合作的重要依據。在本案例中所提出的幾家交易對象,或多或少都與交易對象02有所關聯,因此也間接影響各自的評等分數。新進交易對象05在經由本發明的方法計算交易風險分數後,可藉著直接與間接關聯取得與各交易對象00~04相關的評等分數,最後會將這些分數歸檔並回饋以充實關聯資料庫。After obtaining the transaction risk score of the
已評等過的交易對象,爾後若條件有調整,或者重新調查時,都可以帶入一次本發明的方法,以取得新的評分(即,交易風險分數)。但為了避免交易對象刻意變更條件以取得較高評分,本發明另提出了修正風險評估分數的相關機制。The rated transaction objects can be brought into the method of the present invention once to obtain a new score (ie, a transaction risk score) if the conditions are adjusted later, or when the survey is re-investigated. However, in order to prevent the transaction object from deliberately changing the conditions to obtain a higher score, the present invention also proposes a related mechanism for modifying the risk assessment score.
再以交易對象05為例,假設公司A的人員在使用本發明的方法首次對其進行步驟S110~S150以取得表2中記載的評分(即,41)之後欲再次對交易對象05進行評估,則可重新基於步驟S110至S150求得交易對象05的交易風險分數(以表示)。之後,本發明可依據交易對象05的評分(以表示)修正交易對象05的交易風險分數。Taking the
在一實施例中,交易對象05的修正後交易風險分數可表徵為:
,其中與分別為與對應的權重值,與的總和為1。In one embodiment, the revised transaction risk score of
在不同的實施例中,與可依設計者的需求而選用所需的數值。在一實施例中,為提升的比重(即,較重視當次估計而得的交易風險分數),可選定為小於的數值,但可不限於此。舉例而言,假設為50,為0.4,為0.6,則交易對象05的修正後交易風險分數可估計為46.4(即,((0.4x41)+(0.6x50))/(0.6+0.4))。In various embodiments, and The desired value can be selected according to the needs of the designer. In one embodiment, to enhance (that is, placing more emphasis on the transaction risk score obtained from the current estimate), can be selected to be less than value, but not limited to this. For example, suppose is 50, is 0.4, is 0.6, then the revised transaction risk score of
相應地,公司A內部人員即可基於交易對象05的修正後交易風險分數(即,46.4)作為合作關係考量的依據,並納入關聯資料庫以達到再訓練之成效。Correspondingly, the internal personnel of company A can use the revised transaction risk score (ie, 46.4) of the
綜上所述,本發明的方法可藉由公司或是企業間彼此的關聯程度與歷史交易記錄,分析欲評估的交易對象(客戶或廠商)之交易風險評等。例如,本發明可取得多個交易對象,再根據關聯屬性值建立這些交易對象彼此之間的關聯,並產生關聯矩陣。由關聯矩陣可形成一條或多條走訪的走訪路徑,建立風險關聯矩陣並取得路徑上節點到節點之間的分數,再透過公式計算交易風險評等,最終將交易風險評等反應回交易對象之評分集合,進行風險關聯再訓練。To sum up, the method of the present invention can analyze the transaction risk rating of the transaction object (customer or manufacturer) to be evaluated based on the degree of correlation between companies or enterprises and historical transaction records. For example, the present invention can obtain a plurality of transaction objects, and then establish the relationship between these transaction objects according to the associated attribute value, and generate an association matrix. From the correlation matrix, one or more visiting paths can be formed, establish a risk correlation matrix and obtain the scores between nodes on the path, and then calculate the transaction risk rating through the formula, and finally reflect the transaction risk rating back to the transaction object. Score set for risk association retraining.
本發明可發掘出公司或是企業間彼此的關係,透過多個節點的走訪,最終產生一交易對象風險評等。該評等可有效反應出未來交易行為之潛在風險。並且,本發明可偵測出可疑的交易對象。輸入欲評估的交易對象,即可透過本專利之相關流程,計算出交易風險評等,並回饋至交易對象之評分集合。The present invention can discover the relationship between companies or enterprises, and finally generate a transaction object risk rating by visiting multiple nodes. The rating can effectively reflect the potential risks of future trading behavior. Moreover, the present invention can detect suspicious transaction objects. After entering the transaction object to be evaluated, the transaction risk rating can be calculated through the relevant process of this patent, and fed back to the score set of the transaction object.
由上可知,本發明至少具有以下特點:(1)可發掘出公司或是企業間彼此的關係,並產生關聯評定分數,以供評定交易對象之使用,該評等可有效反應出未來交易行為之潛在風險;(2)可針對首次合作或新進入市場之交易對象,在沒有足夠的資料可參考的情況下,仍可有效進行風險評核;(3)具有回饋學習能力。每次執行風險評等作業,會將交易對象之風險數值納入歷史合作經驗,做為取得風險關聯分數的參考內容。將每次的評估執行結果作為經驗學習,可以減少鉅額交易須承擔過大風險的可能性。另外,將每次的經驗用相同的標準記錄下來,亦可讓優質交易對象與企業之間的關係有更正向的循環;(4)可降低公司承做專標案的未知風險。As can be seen from the above, the present invention has at least the following characteristics: (1) The relationship between companies or enterprises can be discovered, and the associated evaluation score can be generated for evaluating transaction objects. The evaluation can effectively reflect future transaction behaviors (2) It can effectively conduct risk assessment for the first-time cooperation or new market participants, even if there is not enough information to refer to; (3) It has the ability to give feedback and learn. Each time the risk rating operation is performed, the risk value of the transaction object will be incorporated into the historical cooperation experience as a reference for obtaining the risk correlation score. Using the results of each evaluation execution as empirical learning can reduce the possibility of taking too much risk on huge transactions. In addition, recording each experience with the same standard can also make the relationship between high-quality transaction objects and enterprises have a more positive cycle; (4) It can reduce the unknown risk of the company undertaking special bidding cases.
雖然本發明已以實施例揭露如上,然其並非用以限定本發明,任何所屬技術領域中具有通常知識者,在不脫離本發明的精神和範圍內,當可作些許的更動與潤飾,故本發明的保護範圍當視後附的申請專利範圍所界定者為準。Although the present invention has been disclosed above by the embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, The protection scope of the present invention shall be determined by the scope of the appended patent application.
