为什么我用uspto-opendata-python专利搜索得到的结果是“无”？

Question

我试图从美国专利商标局的专利审查数据系统中提取一个特定值(发明人的名字)，但我的代码不会从搜索中获得inventorName值。当我尝试打印结果时，当前的结果是"None“。它确实检索了专利中的所有信息，但我似乎无法获得字典中的特定值。

from uspto.peds.client import UsptoPatentExaminationDataSystemClient
client = UsptoPatentExaminationDataSystemClient()

expression = 'patentNumber:(5555555)'
result = dict(client.search(expression))

print(result.get('inventorName'))
print(result)

目前的结果是：

None<br/>

Answer 1

我找到了另一个可行的解决方案：

import requests
from bs4 import BeautifulSoup
import json

r = requests.get("https://developer.uspto.gov/ibd-api/v1/patent/application?patentNumber=9876543&start=0&rows=100")
soup = BeautifulSoup(r.text, "html.parser")
text = soup.get_text()

r_dict = json.loads(str(text))
print(r_dict['response']['docs'][0]['inventor'][0])

现在，结果就是inventor名称。例如，对于专利9876543，发明人的结果是：

亚历山大，托马斯

进程已完成，退出代码为0

Answer 2

你就快到了！只需深入挖掘一下，因为数据隐藏在'docs'密钥的值中。使用您定义的相同结果对象，您可以通过调用以下命令来获取inventor名称：

result['docs'][0]['inventorName']

对于专利号5555555，它返回'JUN SATO'。

顺便说一句，我认为在可能的情况下，API通常是获取信息的首选方式，支持通过请求/BeautifulSoup进行web抓取。
