Our Premium Search & Compare feature allows you to see the most relevant patent documents for your query. Unlike other patent search engines, we use a novel method of ranking and summarizing the results based on your input text.

Our method is inspired by the techniques of query-focused, extractive document summarization. This means that we identify the most important sentences in each patent document that match your query. We then display only those sentences that have a high score, which you can adjust using the Sentence Score Threshold slider.

How do we score the sentences? We use our advanced Text Keyword Extraction Process to find the most important keywords in your input text. These are the words that co-occur frequently with other important words in your input text. We show you up to 30 top keywords and their confidence values, which indicate how strongly they are related to your query. You can select the keywords that you want to use for scoring the sentences in the patent documents.

We then calculate the score of each sentence in each patent document by adding up the confidence values of the selected keywords that appear in that sentence. We only count the sentences that have at least two keywords in them. We then rank the patent documents by the total score of their sentences that are above the threshold of 100. This way, you can see the most relevant and concise summaries of the patent documents that match your query.
