Patent Landscaping – Gallium Nitride

Introduction

This blog takes a look into the patenting activity around Gallium Nitride uncovering the companies, inventors, and key applications.

GaN is a binary III-V direct bandgap semiconductor commonly used in LEDs. Its wide-band gap of 3.4 eV affords its special properties for applications in optoelectronic, high-power and high-frequency devices. Because GaN offers very high breakdown voltages, high electron mobility, and saturation velocity it is also an ideal candidate for high-power and high-temperature microwave applications like RF power amplifiers at microwave frequencies and high-voltage switching devices for power grids. Solutions that use GaN-based RF transistors are also replacing the magnetrons used in microwave ovens.

Gallium Nitride (GaN) transistor models have evolved from GaAs (gallium arsenide) transistor models; however there are many advantages GaN offers:

  • Higher operating voltage (over 100-V breakdown)
  • Higher operating temperature (over 150°C channel temperature)
  • Higher power density (5 to 30 W/mm)
  • Durable and crack-resistant material

GaN devices are often grown on SiC (silicon carbide) substrates, but to achieve lower-cost GaN devices, they can be grown on sapphire and silicon wafers. GaN’s wide bandgap allows for higher breakdown voltages and operation at high temperatures. The high thermal conductivity of SiC makes it a better substrate than silicon for power amplifier applications that require good heat sinking.

Technology insight report: Contact lens

Introduction:

Contact lens is considered as a medical device that is worn to correct vision. They are also used for cosmetic and therapeutic purposes. When compared with spectacles, contact lenses typically provide better peripheral vision and do not collect moisture such as rain, snow, condensation or sweat.

Contact lenses can be classified in many different ways. They are usually categorized by their primary function, material, and wear schedule. Typically soft contact lens is mass produced, while rigid lenses are custom made to extract specifications for specific individual patients.

One of the important factors that come into consideration when it comes to contact lenses is the kind of material that has been used to produce the lens. Materials have varied through time. In the older times the materials that were used that did not allow much oxygen to reach the eye causing dryness. However technology has changed over the years and so has the availability of products

PatSeer Strategy:

PatSeer creates a centralized work environment for the Intellectual Property and Data Management team to manage and work on patent data projects. Carry out analysis and deliver insights. In the given case of contact lenses, PatSeer created the query as shown in the image below to create the patent set.

Key features of Patent analysis tools Part 2

There are certain key features that every patent analysis tools must possess to deliver holistic results for any Intellectual Property and Data Management firm. In the previous blog post we covered certain features like patent text mining function, analytical capabilities and search functionality which play a crucial role in providing holistic delivery and intelligence information around patents.  Apart from these there are certain other add-on features which are necessary to build an efficient Patent analysis tool.

1)      Charting and visualization:

The power to convert patent analysis data into charts and powerful graphics is a must have feature for any patent analysis tool.   It comes really handy to have a visual representation of data to export them into reports and presentations. The visuals are usually in the form of pie chart and bar graphs showing the change in patent trends and dominance of a particular segment over the other. A good visualization and reporting component helps convey the insight easily without any need for explanation. Powerful visuals necessitate actions from the information consumers’ typically senior management and result in swift decision making. VIZmap is a visualization module available  with Patent iNSIGHTS Pro for users who seek advance visualization above charts and graphs for semantic exploration within large sets of patent data.

 

Capture

[Figure 1]

2)      Reporting:

 One of the major needs of any organization will be generating reports of various types to suit the need of a particular department. Support for a wide range of flexible report types is useful with output format as word or excel so that the user can modify the report as per needs after it has been generated.

If we take an example of 3D printing , Patent iNSIGHTS Pro generated reports based on research activities around the world for 3D printing. The focus was on generating key statistics   about the companies leading in the domain. We used the the Assignee 360 report option to filter  the top companies and generate the report. The generated report  is then  exported to excel and for further customization  or editing.

 

3)      User Interface and ease of usage:

 There is always a demarcation between patent analysis tools armed with numerous features and one which is simple to use for an average employee. This becomes one more demarcating feature for opting for a patent analysis tool for your organization.  A good solution to this would be: opt for a tool which has an easy to use interface. A very easy to use interface may not always give you that flexibility and range of customization while an extremely complex interface may defeat the purpose and make the process of analyzing data more tedious rather than easier. Look out for an interface which gives you both ease of use along with flexibility of options.

These are the most sought after qualities that an Intellectual Property and Data management organization should look  for while opting  for a patent analysis tool .  Apart from the above mentioned features,  organizations should also look for capabilities like data export, associating custom fields with patent data, a rating or scoring system for measuring performance and quality of data being dealt with.

Key features of Patent Analysis Tool Part 1

Patent analysis tools are developed to provide holistic delivery information and intelligence around patents. They are mostly distinguished in terms of their features and delivery capabilities. In an Intellectual Property and Data Management organization if you are looking for a particular Patent tool to serve the purpose of your organization then ideally what should you be looking out for?  Here is the overview of the various important features found in the most comprehensive patent data analysis tool and what components should you look out for while deciding upon during the evaluation process.

 

1)      Search capabilities: Why should one look out for search analysis in the patent analysis tool when most of the search is already done in the database?  This can be further elucidated with the answer to another question.  What is search in patent analysis? Searching is usually a requirement for custom portfolio, categorization and further it is absolutely critical when going ahead with deeper analysis. Even when looking at a chart, it is important to be able to immediately drill-down from the chart and search through the segmented portion to get to the answer or insight you seek. Finally at lot of time it is absolutely essential to have custom fields such as tags, comments etc. These requirements make it essential to have reliable search capabilities in the analysis tool that you are opting for.

2)      Patent Text mining functions: When working with sets of 10000 records or more if you want to quickly understand what locate topics of interest or sometimes even understand which topics are prominent across the set and what sub-topics they are associated with, a powerful tunable auto-categorization engine is a must. Solutions that are created specifically for mining and clustering patent text are better suited than more general text mining solutions. Generating keyword lists and using such list for statistical analysis is another popular method used to gain insights on trends across companies, inventors and their patents.

3)      Analytics capabilities: One of the major capabilities that should be under the coverage of a patent analysis tool is a co occurrence matrix generating top lists and citation analysis. This feature helps in analysis and spotting trends within certain specific trends or technologies to have better insights into the future of these trends. It’s always good to get a few analytics questions that your organization has, tested and verified using the analytics capabilities so that you are sure if the solution is up to the task of handling your patent intelligence needs.

There are more to the list which one should keep in their mind while looking for a patent analysis tool such as data export features, associating own custom fields with patent data, rating and scoring system. Details analysis of these trends and characteristic features will come up in our next post, a continuation to ‘Key features of patent analysis tool part 2’.

Technology landscape: Nanofabrics

Nano fibers are defined as fibers with diameter less than 100 nanometres. They are basically small group of atom and molecules with radius of less than 100 nano meters. Particles on the nano scale have a very high surface area to volume ratio, whereas this ratio is much lower for objects on the macroscopic scale.

Nano fiber is engineered to give advantages to ordinary materials making them resistant to odor, moisture and other degrading properties. It helps to increase their elasticity, strength and bacterial resistance. Depending upon the property, a nano fabric is constructed either from nanoscopic fiber called nano fiber or it formed by applying a solution containing nano particles to form a regular fabric.

Nano fiber has huge application in various domains ranging from pharmacy, apparels, medical application beverages and more. Application of nano fiber has the potential to revolutionize textile manufacturing and area of medicine such as drug delivery and tissue engineering.

Patseer Search strategy:

Patseer is a cutting edge technology tool which is smartly equipped to search though vast patent databases, sorting, filtering, analyzing and creating reports. It is a result of outstanding algorithms to bring the word “tedious” out of the business equations and bring out a fresh web 2.0 approach to searching, analyzing, comparing and collaborating and managing patent data.

Patseer was used to develop a particular search query to search and develop the particular patent data set. The search query is shown in the image below.

TAD: Title, abstract and Description

TADC: Title, abstract, description and Claims

IC: International Class

 

image11

 

How it works:

The query was directed to search through the title, abstract and claims with one publication per family was generated and imported in Patent iNSIGHT Pro.

After reviewing few results esp. from older publications, we came across some similar but irrelevant terms which we then excluded from full text and irrelevant class were also excluded using NOT operator. And finally a patent set of 3262 records are obtained.

Technical segmentation: Categorization Tree

The categorization tree shown below shows the different categories and the number of records in each of them. The categorization involved defining a search strategy for each topic and then conducting the search using the Advanced Searching capability in Patent iNSIGHT Pro.

Top Players:

Once the patents were populated in Patent iNSIGHT Pro, the assignee clean up tools were used to

normalize the names.

Different cleanup tools were leveraged

• To locate assignees for unassigned records

• To clean up records having multiple assignees

• To locate the correct assignee names for US records using the US assignments database

• To merge assignees that resulted from a merger or acquisition or name change.

The dashboard tool within Patent iNSIGHT Pro was used to find the top 20 assignees

within the given patent set. A visual graph was created based on the results of the top assignees with the number of patents alongside each one.

Patent Landscaping -3D printing

3D printing or additive manufacturing is a process of making three dimensional solid objects of any shape from an existing digital model.  The additive process of 3D printing indicates successive layers of material laid upon each other to form the desired shape. 3D printing is quite a refreshing change from the traditional machining technique which relies mostly on removal of material by cutting or drilling, also known as the subtractive process.

The term additive manufacturing refers to the technology that creates objects through sequential layering. The 3D printing technology is used for both prototyping and distributed manufacturing with applications in architecture, construction (AEC), industrial design, automotive, aerospace, military, engineering, civil engineering, dental and medical industries, biotech (human tissue replacement),fashion, footwear, jewellery, eye wear, education, geographic information systems, food, and many other fields.

PatSeer Strategy:

 PatSeer which is smartly designed to sort, filter, create and analyze reports can be used to create queries to search and obtain records with respect to 3D printing. The following search query was created to sort 3D printing across various segments.

1)      TAC: Title, Abstract, Claims

2)      TACD: Title, Abstract, Claims, Description

3)      IC: International class

4)     CPC: Cooperative Patent Classification

These queries are directed to search through Title, abstracts and claims. The individuals are then collapsed into one publication per family which is then exported from PatSeer and then imported to Patent iNSIGHT Pro.

In the search query shown in ( Fig 1 ), result set of 2863 records were imported into the software.

False Positives:

 After the result sets were obtained, the few discrepancies such as unwanted and confusing terms were eliminated to arrive at a result set of 2635 records which formed the base for further analysis.

The elimination process involved removing all files with filling dates before 1990; irrelevant words like 3D colours and printing of 3D images were removed to create a very relevant and acute database.

Patent categorization:

 To analyze patents under 3D printing they are categorized under 3 broader categories mostly by technology, by material and by industry as shown in the image below.

Publication Trends:

What was the publication trend in 3D printing?

Once the patents were populated in Patent iNSIGHT Pro, the publication trend chart was generated on a single click using the dashboard tool. Innovation in 3D printing and its resulting patent publications started to show up from the 1990s with the real surge in the activity around this technology happening in the last 5 years. It’s clear the current activity around these technologies is likely to continue seeing more innovation in the near future.

The trends can be pictorially depicted in the image given below:

Top Companies in 3D printing:

 The following methodology was adopted to determine the leading names in the domain of 3D printing. Once the patents were populated in Patent iNSIGHT Pro, the assignee clean- up tools were used to normalize the names. Different cleanup tools were leveraged:

• To locate assignees for unassigned records

• To clean up records having multiple assignees

• To locate the correct assignee names for US records using the US assignments database

• To merge assignees that resulted from a merger or acquisition or name change.

 The dashboard tool within Patent iNSIGHT Pro was used to find the top 20 assignees within the given patent set. A visual graph was created based on the results of the top assignees with the number of patents alongside each one.

How was the result obtained?

 First various technologies were identified by manual research. Then by using a combination of semantic analysis tools such as clustering tools and searching tools available in Patent iNSIGHT Pro, records were categorized under different technologies. A co-occurrence matrix was generated using the co-occurrence analyzer to map the different technologies with assignees. The matrix was filtered for the top 15 assignees and was converted into bubble chart using the option provided in software for the same.

Landscape for technologies used for 3D printing

A patent landscape analysis will helps in gaining an overview of a technology sector, competitors and chronological developments in a particular field of technology.

In addition, it can also help you to better evaluate the economic value of a patent portfolio.

A patent landscape analysis helps in identifying the following:

  • The current trends in focus of companies, industries and countries
  • Technology leaders and their IP strategies and their business decisions
  • Technological positioning of companies and their chronological changes
  • Unique selling points of companies
  • Strengths and weaknesses of patent portfolios

The contour map below represents different materials used for the production of 3D objects with respect to complete patent portfolio. Clusters for Stereolithography and photolithography are close to each other as there is high degree of relevance between the records present in those technology areas. The patents represented by dots were coloured by company.

[Figure 6]

The VizMAP tool of patent iNSIGHT Pro is used for this purpose. First the clusters for different materials were loaded on the map. They were analyzed on basis of their contextual similarity using title, abstract and claims as Text and technology as UDC from the ‘Context mode’ option. We removed unrelated patents using the “Hide Unrelated records” option and one patent assignee using the options available in VizMAP.
