Filter insert

Patent Number: 5,618,324

Patent Information

A filter insert for the filtering of the fresh air supplied to a motor vehicle interior has an accordion-folded filter element which is self-supporting. Lateral strips coated with an adhesive are provided on the faces which extend on the left and on the right. On the faces which extend in parallel to the folding, angle strips are arranged whose first leg extends along at least three fold edges. The filter element is surrounded along the faces by a foamed-material sealing.

PatentStat Scores in Not categorized
These scores show the percentile ranks for each metric.
For example, a score of 90 means that 90% of similar patents had lower scores.

Patent Grant Time

This patent had ► Log In grant time compared to others in this category.

Patent grant time can be influenced by many factors. Activities within the USPTO that are beyond the control of patent attornies can influence grant time, but short grant times can also indicate well-written patents and dedicated efforts to respond rapidly to USPTO office actions with strong arguments. Shorter grant times are preferable, and the scores for this section are inverse measures — higher scores are better.

Patent Claims

This patent has ► Log In claims compared to others in this category.

The number of claims in a patent is correlated with its strength. Because greater claim counts increase the cost of a patent, more claims can indicate the importance an applicant assigns to a patent. Importantly, some may elect to file claims across multiple patents. A higher score in this metric indicates more claims, relative to others in this category.

Citations From Other Patents

This patent has received ► Log In citations from other patents, than others in this category.

Citations from other patents are an important measure of the significance of a patent. More citations indicate that other technologies build on a patent. Higher scores in this metric are better, and indicate more citations from other patents.

Citations to Other Patents

This patent referenced ► Log In citations to other patents, than others in this category.

A lower number of citations to other patents can be a sign of diminished patent strength. More citations indicate dependence on more other technologies. Higher scores in this category are better, and indicate fewer citations to other patents.

Research and Innovation Indicators
These are percentile ranks — they indicate the percentage of peers with lower scores.

Proximity to Basic Research

► Log In


Proximity to Basic Research

This patent has ► Log In proximity to basic research compared to others in this category.

Proximity to basic research is measured by comparing the number of citations to non-patent literature among a cohort of patents. Because most non-patent citations are primary research papers, a higher count indicates greater proximity to basic research.
