Python 查询多个受让人组织的专利的PatentsView

我正在尝试从PatentsView获取多个组织的专利。示例可在

http://www.patentsview.org/api/query-language.html

这是我的疑问：

import csv
import requests
import json

# Use this format for GET requests
url = 'http://www.patentsview.org/api/patents/query?q={"_and":[{"inventor_last_name":"Jobs"},{"assignee_lastknown_country":"US"}]}&f=["patent_number"]'

# This format is for POST
url1 = 'http://www.patentsview.org/api/patents/query'

# String contains the value string (http://www.patentsview.org/api/query-language.html)
body = '{"q":{"_contains":{"assignee_organization":["Samsung","Apple"]}},"f":["assignee_organization"]}'

url2 = 'http://www.patentsview.org/api/patents/query?q={"_contains": {"assignee_organization":["Samsung","Apple"]}}&f=["assignee_organization","patent_number","patent_title"]'

r = requests.get(url2)
# r = requests.post(url1,body)

print r.text

查询的输出为：

由于某种原因，服务器在“代码>受让人组织< /代码>名称中考虑‘数组’。使用单个公司名称运行相同的请求似乎可以正常工作

解决此问题的好方法是什么？

看起来这是PatentsView API as works中的一个bug

但是，如果您使用如下所示的“\u或”运算符，则它可以工作。注：我必须为三星嵌入一个“_contains”，作为API检查平等性，正确的受让人名称是“三星电子有限公司”

PatentsView-dev在这里，感谢您提出这个问题！我们发现_contains运算符的列表参数错误，现在您的原始API调用应该给出正确的响应：

刚刚向PatentView支持部门发送了一封电子邮件，告知他们这一点。感谢您的更新。有没有办法获取有关专利的所有文本？我很高兴发布一个单独的问题。当然，下面是如何获得专利的标题和摘要：--“f”参数需要一个输出字段列表，这页上有一个完整的列表：--希望有帮助：）

import requests
url = 'http://www.patentsview.org/api/patents/query?'

query='q={"_or":[{"assignee_organization":"Apple"},{"_contains":{"assignee_organization":"Samsung"}}]}'
query+='&f=["patent_number","patent_title","assignee_organization","inventor_last_name"]'

results = requests.get(url+query)
results=results.json()

for r in results['patents']:
    print(r)
