USPTO專利資料庫使用筆記

資料庫包括三種專利資料：

- US-PGPUB（自3/2001尚未獲准的申請案）

- USPAT（自1970年至今的美國專利、專利號碼與分類可查到1790年）

- USOCR（1970年之前的文字辨識的專利檔案）

上圖空白欄位用以填入搜尋字串，這是不分欄位而通篇文章的搜尋方式，搜尋頁面預設有三塊，左上就是搜尋欄，左下則是檢索結果的列表，右方則是用來預覽所選擇的檢索結果。

也可改變layout：

搜尋指令可以參考以下表格，用來指定搜尋的專利欄位，與舊版不同，所以老手要重新習慣了!!!

基本搜尋範例：

ex. "pmbus" and "floating point" and "decoding"

使用"Wildcards"的搜尋範例：

（"?"是一個缺字字元、"$5"是指5個缺字的字元、"*"或"$"不限數量的缺字）

ex. "p?bus" and "floating$5" and "decod*"

布林算符：

Operator	Description	Example	Behavior
AND	Two terms, joined by "AND" must occur within the same document.	photographic AND noodle	Returns all documents that contain both the terms "photographic" and "noodle" somewhere in the document - regardless of their order.
OR	Two terms, joined by "OR" means at least one of the terms must occur in the document.	dog OR cat	One of these two terms must occur in the document.
NOT	The first term must occur, the second term must not.	cardboard NOT box	Returns documents where the term "cardboard" does occur in the document, and the term "box" never occurs in the document.
XOR	Two terms, joined by "XOR" means at least one of the terms must occur in the document, but not both terms	pipe XOR ptfe	One of these two terms must occur in the document, but not both terms.

接近算符：

Operator	Description	Example	Behavior
ADJ	Two terms must occur directly next to each other, and in order. ADJ is the only ordered operator.	oxidizing ADJ bacteria	Returns documents where these two terms occur adjacent to each other and in the same order. This is the default operator, and is applied when no operators are given.
ADJ[n]	Two terms must occur within [n] terms of each other, in order, and within the same sentence.	wet adj4 silicon	The term "silicon" must occur within the 4 words that follow the term "wet" - so the following "wet oxidized, polysilazane-based silicon oxide" would be considered a hit. Maximum value of N is 450.
NEAR	Similar to ADJ but order is not relevant.	electrospray NEAR ion	Returns documents where the terms "electrospray" and "ion" are next to each other and in the same sentence, but in any order. So unlike ADJ, this search would return a hit for "negative ion electrospray"
NEAR[n]	Again, similar to ADJ[n], but order is not relevant.	cyclotron NEAR7 magnetic	Finds documents where the term cyclotron is within 7 words or the term magnetic - regardless of order. This would hit the following "a magnetic sector mass analyzer, or an ion cyclotron." Maximum value of N is 450.
WITH	Terms joined with WITH must occur within the same sentence.	detect WITH light	Finds documents where the terms "Light" and "detect" occur within the same sentence.
WITH[n]	Terms joined with WITH must occur within n sentences of each other.	detect WITH10 light	Finds documents where the terms "Light" and "detect" occur within 10 sentences of each other. Maximum value of N is 25.
SAME	Term joined with SAME must occur within the same paragraph.	synthesizing SAME tomography	Very similar to WITH but the searches occur over paragraphs rather than sentences.
SAME[n]	Two term just occur within n paragraphs of each other.	wheel SAME3 wood	Very similar to WITH[n] but the searches occur over n paragraphs rather than sentences. Maximum value of N is 25.
