Domain Collection: The principle focus of this report is to create a broad patent landscape around the software-defined virtualized networking intellectual property domain. The broad domain collection for this report was created by matching the phrases "network virtualization" AND ("software defined network" OR "software-defined network") anywhere in the title, abstract, description or claims of the patent documents available in Google’s BigQuery data warehouse in the patents.publications dataset. These phrases are queried in a logical fashion such that the matching of these phrases in any of the specified sections, will include that patent document in the domain collection. The patent documents query was executed on a worldwide basis across all US and international patent documents contained in Google’s dataset. See the Summary of All Patent Documents in the Domain Collection for more information or to execute additional queries into the domain collection documents.
"network virtualization" AND ("software defined network" OR "software-defined network") – matched on a worldwide basis in patent documents title, abstract, description, or claims.
The resulting domain collection consists of 3,477 total documents of which there are 2,072 patent applications and 1,477 granted patents.
Patenting Activity: Patenting activity in this IP segment is relatively new, with the first patent applications filed just 12 years ago in July 2011. In fact, there were 14 patent applications file in July of 2011 all on behalf of Nicira Inc. These patent applications resulted in the first granted patents in this IP segment in 2014 and 2015. Nicira Inc. was a Palo Alto, California based company that was an early innovator specifically in the area software-defined virtualized networking. The company was founded in 2007 and was subsequently acquired by VMware in July of 2012 . Following those first application filings, activity remained relatively modest through 2012, after which activity increased nearly five fold in 2013 and continued to increase through 2017. The vast majority of patenting activity in this domain collection has occurred over the last 9 years since approximately 2014. Current numbers generally indicate that there are approximately 350 to 425 new applications and 140 to 190 granted patents annually. See the Domain Collection Date Coverage Table and the Patenting Trends Timeline for the Domain Collection .
Patenting Trends: The pendency period for granted patents (i.e. the time between application and patent approval), over the relatively near-term active filing period from 2017 through 2020 has varied from ~34 months to as low as ~24 months, with the most recent data indicating a pendency period of 2.0 to 2.5 years. This indicates that the most recent 2.0 to 2.5 years of data in the patenting trend charts ( Patenting Trends Timeline for the Domain Collection ), 2020-2023, are likely incomplete data. As a result, the Applications and Granted Patents Timeline is indicating generally flat to somewhat declining patent application filing trends with 350 to 425 new applications filed annually. The granted patent approval percentage trend since 2017 has remained relatively flat at approximately 40% to 45%. See the Approval Rate (%) and Pendency Period charts. The relatively high-level and flat to declining application filing trends, combined with the flat approval rate, together indicate a generally stable patenting environment.
Top Inventors & Their Assignees: Of the top 10 inventors in this domain collection, individuals associated with Nicira and VMware occupy 7 of the top 10 spots, including the top 6 positions. The leading inventor is clearly Teemu Koponen who is listed on 127 patent documents and was a founding employee and engineer with Nicira. Mr. Koponen looks to currently be a founder of Styra, Inc. , which is a company focused on software and infrastructure policy management for enterprise cloud environments. The 2 nd ranked inventor is Pankaj Thakkar , who is listed on 94 patent documents and was a senior software engineer with Nicira. Mr. Thakkar is currently a co-founder of KloudFuse Inc. , which focuses on systems observability software. The 3 rd ranked inventor is Martin Casado , listed on 66 patent documents. Mr. Casado was a founder and the CTO of Nicira and is currently a General Partner a the venture capital firm Andreessen Horowitz . The 4 th ranked inventor is Ronghua Zhang , who was a senior software engineer for Nicira and is now a developer at Databricks . The 5 th ranked inventor is Jeremy Stribling , who was also a senior software engineer for Nicira and is now a developer for Zoom Video Communications, Inc . Other inventors ranked in the top 25 also include additional individuals associated with Nicira or VMware. Also noteworthy in the top 25, is the presence of inventors from Ericsson, which as noted below is one of the leading assignees in this IP segment. For more information see the Top Inventors and Principal Assignees table and the complete list of 3,106 inventors.
IP Competitive Landscape (Top Assignees): The top 25 assignees in this domain collection consists almost exclusively of the world’s largest networking and telecommunications companies, with the patent documents concentrated somewhat with the top three assignees. The top assignee is VMware as a result of the company’s patent filings and its 2012 acquisition of Nicira Inc . The 2 nd , and closely ranked assignee, is Ericsson , a large telecommunication company headquartered in Stockholm, Sweden, and Cisco Systems rounds out the top three. These top three assignees account for approximately 60% of the patent documents of the top 10 assignees. The 4 th ranked assignee is Juniper Networks Inc. , listed on approximately half as many patent documents as Cisco. The 5 th ranked assignee is Intel Corporation .
The remaining assignees that make-up the top 25 consist mostly of a mix of large telecommunications, networking, and software companies. One smaller company of note, with a generally over-sized patent document position relative to its corporate size, is Parallel Wireless , a private company based in New Hampshire that's focused on 5G OpenRAN wireless systems. Despite the company's relatively small size, it ranks 12 th on the top assignees list. One final company of note in the top 25 is NxGen Partners LP , which looks to be a patent holding company with a significant position in this IP sector and a ranking of 23 rd overall (index #25 in the Top Assignees list). In general, patent holding companies can sometime be viewed as risks to an IP sector due to the potential for these companies to pursue aggressive licensing and litigation business strategies. For more information see the Top Assignees table and the complete list of 506 assignees.
Top Cited Patent Documents & Citation Assignees: The top patent document citations across the domain collection have assignees that include many of large companies in the assignees list that were early innovators in software-defined virtualized networking as well as a number of other companies, sometime from diverse technology segments, that provided supporting innovations. This includes companies like Juniper Networks, VMware, Nicira, and Cisco, as well Marvel Technology , Fortinet Inc. , and Bay Networks Group ( acquired by Nortel in 1998 , with the IP assumed to be part of Nortel’s IP liquidation in 2011 ). The top three patent document citations were granted patents to Juniper Networks and focus on fundamental technology for network packet switching. The 4 th ranked patent document citation was a patent granted to Marvel Technology that deals with network bridging technology between two or more networks. Rounding out the top five citations is one originally granted to Bay Networks Group that pertained to configuration support for a virtual networks. Most all of the top 10 patent document citations were approved as granted patents and many have since expired as enforceable intellectual property. However, these patent documents, and all the others in the citations table, still serve as prior art references to new technology developments in this IP sector. So, its generally a good idea for new technology developers to be at least somewhat familiar with these patent document citations. See the Top 100 Patent Document Citations table below.
When the top 100 patent document citations are sorted by assignee, Juniper Networks ranks as the assignee with the most prominent citations portfolio. Interestingly however, Amazon Technologies, Inc. ranks as the assignee with the second best citations portfolio. IBM, Hitachi, and Cisco round out the top five patent document citations portfolios. See the Top Patent Document Citations, Sorted by Assignee table for more information. Also review the Top Non-Patent Literature Citations table for the top 100 citations from articles, research reports and media references.
Top Technology Classification Codes: The top inventive CPC technology classification codes for this domain collection focus on the principal components involved in software-defined virtualized networking, namely digital communications, the processing of digital information (i.e. the software aspects), and even wireless communications. This includes CPC Group Codes of H04L (“TRANSMISSION OF DIGITAL INFORMATION, e.g. TELEGRAPHIC COMMUNICATION”), G06F (“ELECTRIC DIGITAL DATA PROCESSING”), and H04W (“WIRELESS COMMUNICATION NETWORKS”). Group Code Number sub-classifications cover additional detail in the administration and routing of packet switched networks, programmatic control of networks, network security, protocols, and connection management. See the Top Inventive CPC Group Code Numbers table for more information and the list of the top 250 CPC classification codes with descriptions searchable via keywords and phrases. It is also possible to use the Patent Documents Summary table to search on the applied CPC codes to find specific patent documents to which certain CPC codes have been applied.
Additional Domain Collection Queries:
Executing additional queries into the domain collection, via the Summary of All Patent Documents table, can often provide additional insight into sub-topics contained in the domain collection that may be of more specific interest. This can be accomplished by showing the relevant sections of the patent documents (title, abstract, or claims) or additional metadata fields, and executing additional keyword, key phrase, or parameter queries via the provided column search fields. Whenever switching between shown and hidden column fields, it’s important to clear the column field search box before hiding the field. Entering data into multiple column search fields will produce the ANDed results of those separate searches. So, if a field column is then hidden with a value or keyword in the search field box, that will still be applied in the ANDed search results. Also remember that the “Patent Claims Text” field is only available for US patent documents, not international patent documents, as supplied via Google’s BigQuery patent dataset. Below are some examples.
For example, say we’re interested in finding all patent documents with a filing date year of 2020 that also contains the word “wireless ” in the title of the document. With the fields shown as indicated below (green highlighted fields are show in the table), we can use the search fields above each column to execute an ANDed query into the table of patent documents. Entering the year “2020” in the “PatApp Filing Date” column search and “wireless ” into the “Patent Title” column search will show all patent documents matching both of those parameters. There are 16 results total from the domain collection of 3,477 documents with the five most recent documents show below.
In addition, say we’re interested in finding all patent documents that have the word “ingress” and the phrase “virtual tunnel endpoint” in the abstract of the document. First, we show the “Patent Abstract Text” field and then enter the word “ingress” and the phrase “virtual tunnel endpoint” (enclosed in quotes) as show below. This indicate that there are two patent documents that match this query, both from VMware.
Table of Contents:
Summary of All Patent Documents in the Domain Collection
Provides an interactive, searchable, sort-able table of all patent documents in the analysis domain collection, including a variety of metadata fields pertaining to the documents. The titles, abstracts, and claims of the patent documents are also provided and can be further queried via the column-specific and overall search capabilities. This interactive table is useful in executing additional queries on the entire domain collection, such as keyword or key phrase queries on claims to find specific claims of interest, finding patent documents from specific inventors or assignees, or searching and sorting on various date fields such as filing date, grant date, or earliest priority date.
Duplicate patent documents, potentially filed with various international patenting authorities, have been deleted. So, there’s only one representative patent document per patent family.
Provides a table summarizing the date coverage, listing the earliest and most recent dates for filed patent applications, published documents, granted patents, and priority dates. This table provides some basic context to help profile the domain collection and summarizes the date ranges of documents included in the analysis.

Patenting Trends Timeline for the Domain Collection
Provides timeline of the number of patent applications and granted patents, and thus shows a concise view of the historic patenting trends embodied in the domain collection. In addition, line charts show the timelines for the approval percentages and pendency periods. These charts can be used to assess the competitive nature of the patenting environment for the domain collection IP segment.
Top Inventors and Principal Assignees
Provides a table of the top inventors listed on the patent applications contained in the domain collection and essentially identifies the top intellectual property experts of the domain area profiled. This table also lists the entities (corporations, educational institutions, etc.) to which those inventors have assigned the predominant number of patent applications, and thus identifies relationships between inventors and those assignees.
Provides a table of the top assignees of patent applications contained in the domain collection and largely represents the competitive landscape from an intellectual property perspective. These assignees are the corporations, educational institutions, individuals, and other entities, that are involved in the IP sector, and thus may also be prospective development partners, investors, IP acquirers, or IP acquisition targets.
This table can also be helpful in identifying entities that may be patent holding companies, otherwise know as non-practicing entities (NPEs). These companies typically acquire or develop IP portfolios and then employ licensing or litigation business models that can increase costs and risks for other companies competing in the IP sector.
Finally, a review of the companies in the lower quartiles of this list can also identify start-ups and emerging companies that are just beginning to established patent portfolios in the IP sector.
Top 100 Patent Document Citations

This table provides some basic context to help profile the domain collection and summarizes the date ranges of documents included in the analysis.
- Provides a table summarizing the geographic distribution of patent applications and granted patents by country contained in the domain collection. This table is also provided to help profile the documents included in the analysis.
- Google's BigQuery 'patents.publications' data table contains full text information (titles, abstracts, descriptions, and claims) on US patent documents but only titles and abstracts on international patent documents. As of the date of this report, the BigQuery data table does not contain full text descriptions and claims for international patent documents. As a result, the geographic coverage insights can vary depending on the type of query that was used to generate the domain collection. Semantic keyword or key phrase matching queries that include international patent documents, only query and match those keywords and phrases across the titles and abstracts of those international documents. Thus, the results for semantic queries may be biased toward US patent documents.

- Shows a bar chart timeline of the number of patent applications and granted patents, and provides a concise view of the historic patenting trends embodied in the domain collection. In addition, line charts show the timelines for the approval percentages and pendency periods. These charts can be used to assess the competitive nature of the patenting environment for the domain collection IP segment.
- More specifically, the bar chart shows the number of patent applications filed on an annual basis beginning with the earliest application in the domain collection and ending with the most recent filing in the domain collection.
- The granted patent totals have been time-shifted so that the granted patents align with the corresponding applications and thus correctly reflect the granted patents resulting from the applications of a given year.
- The pendency period line chart can be used to assess the validity of the data shown in the applications and granted patents bar chart as well as the approval percentages line chart. For example, with most patenting authorities, such as the USPTO, there is some delay in publishing patent applications and typically a longer time period between application and granted patent (pendency time). For the USPTO, most patent applications are published 18 months after the filing date and pendency times for granted patents can be 24 months or longer. This typically indicates that the most recent 18 to 24+ months of data reflects only partial results.
- Note that the horizontal axis may not reflect a consecutive linear year progression if there were years where there was no patenting activity and no data exists.
- If the domain collection represents a mix of international patent documents, note that these patent documents are often subject to varying examination and approval procedures of different worldwide patenting authorities, which can result in skewed data for the charts below. For example, patent documents from China, that utilize China's utility model patent process, can have notably shorter pendency periods, which can skew the pendency results shown below.

- Provides a table with the same information as the previous Top Patent Document Citations table, except this table is sorted by assignee and is designed to identify the assignees with most significant intellectual property positions across the domain collection based on the total number of citations. This table aims to clearly show the corporations, educational institutions, individuals, or other entities that have broad positions in the IP sector profiled by the domain collection.
- Like the previous table, the “Number of Patent Docs” column indicates the number of times the citation was referenced across all applications in the domain collection.
- The “Tot Num of Patent Docs” column indicates the total number of patent application citations on an assignee basis. This number is computed by examining the citations per assignee and then summing the number of times those citations are referenced across the domain collection. The default sorting of the table ranks assignees in descending order of “Tot Num of Patent Docs” and thus provides an indication of the assignee’s intellectual property position in the domain area.
- Click on column headings to sort.

- Provides a table of the top inventive CPC group codes and CPC group numbers (and respective CPC titles) that are assigned to patent documents included in the domain collection. This table essentially provides two levels of description into the inventive ideas embodied in the domain collection and is designed to provide some technological descriptive context to the patent documents of the IP segment profiled.
- The CPC group code is shown as the first four alphanumberic characters of the "CPC Group Code Number" field. This represents a macro-level description of the inventive ideas. The CPC group number is represented as the numeric digits following the group code and represents an additional level of detail. Thus the "CPC Group Title" and "CPC Group Number Title" together provide two levels of description of the inventive technologies used in patent documents across the domain collection.
- The “Percent of Top 250 Group Numbers” column indicates the concentration of the inventive ideas in the designated CPC group number across the top 250 group numbers in the domain collection. Patent documents can be assigned multiple CPC codes representing potentially different inventive ideas embodied in the document.
- Click on column headings to sort.
