Relativity and X1 Publish Updated Joint Legal Whitepaper on ESI Collection Best Practices

By John Patzakis

Relativity and X1 have published an updated joint legal whitepaper addressing full-disk imaging as a disfavored collection practice in civil litigation, with Relativity eDiscovery attorney David Horrigan as the lead author. This paper is a substantive update from the original published a year ago, adding discussion of important and relevant new case law published in the past 12 months. The paper notes that “if the preliminary data from the first five months of 2022 are any indication, we may be seeing that the law of proportionality is becoming more settled — and that courts continue to disfavor full-disk imaging.”

The paper delves into all the legal reasons, including detailed analysis of case law, the Federal Rules of Civil Procedure, and the Sedona Principles establishing why forensic collection is not required in civil litigation. The paper primarily focuses on the principles of proportionality in its legal analysis as well as case law issued prior to the 2015 amendment to the Federal Rules of Civil Procedure, which gave greater prominence and clarification of the proportionality rules.

One of the recent updated cases included is Besman v. Stafford, where the appellate court reversed and remanded a trial court’s order of a forensic examination of a law firm computer, holding the trial court erred in failing to take precautions to protect the privileged and confidential information on the device. “Generally, courts are reluctant to compel forensic imaging, largely due to the risk that imaging will improperly expose privileged and confidential material contained on the hard drive,” Judge Anita Laster Mays wrote for the appellate court.

This is an important topic as a key problem in eDiscovery that drives inefficiencies and higher costs is that default collection methods often involve full-disk imaging—a forensic examination of an entire computer—when searching for responsive data. As the whitepaper notes, “it turns out full-disk imaging is not required for most eDiscovery collections. In fact, courts often disfavor the practice.”

Industry Experts: Proportionality Principles Apply to ESI Preservation and Collection

By John Patzakis

Under Federal Rule of Civil Procedure 26(b)(1), parties may discover any non-privileged material that is relevant to any party’s claim or defense and proportional to the needs of the case. Lawyers that take full advantage of the proportionality rule can greatly reduce cost, time and risk associated with otherwise overbroad eDiscovery production. In a recent webinar, eDiscovery attorney Martin Tully of Redgrave LLP, addressed how to use processes and best practices to operationally attain this goal, particularly in the context of preservation and collection. In addition to being a partner at the Redgrave firm, Tully is currently the chair of the Steering Committee of the Sedona Conference Working Group on Electronic Document Retention and Production (WG1), providing additional import to his comments on the subject.

During the webinar, Tully noted that the “duty to preserve is directly aligned with what is within the scope of discovery….so if something is not within the scope of discovery – that is its either not relevant or its not proportional to the needs of the case — then there should not be an obligation to preserve it in the first place.” Tully discussed at length the recent case of Raine Grp. v. Reign Capital, (S.D.N.Y. Feb. 22, 2022), which holds that under FRC 26(a), parties “have an affirmative obligation to search for documents which they may use to support their claims or defenses.” In meeting these obligations, the court provided that a producing party may utilize search methodologies, specifically mentioning search terms. Tully explained that the court—in addressing the concept of reasonable, proportional discovery under the Rules – provides that producing parties are obligated to search custodians and locations it identifies on its own as sources for relevant information as part of its obligations under Rule 26, but that such identification and collection efforts should be proportional.

Further to these points, Tully weighed in on overbroad practice of full-disk imaging, noting that it should not be the default practice for eDiscovery collection: “Too often there is a knee jerk approach of ‘let’s just take a forensic image of everything – just because.’” According to Tully, alternative and more targeted search and collection methods were more appropriate for eDiscovery and can better effectuate proportional efforts: “Indexing in-place is key because it doesn’t just preserve in-place and reduce costs, but it can give you insight (into the data) to further justify your decision not to collect it in the first place, or if you need to, you are in much better shape to go back and collect the data in a tailored and focused way.”

Co-presenter Mandi Ross, CEO of Insight Optix also provided keen insight, outlining her typical workflow applying the aforementioned proportionality concepts through custodian and data source ranking and keyword searching performed in an iterative manner to identify key custodians, data sources, and the potentially relevant data itself. To effectuate this, Mandi noted that the enterprise eDiscovery collection and early data assessment process should enable a targeted, remote, and automated search capability, with immediate pre-collection visibility into custodial data.

In fact, both Tully and Ross emphasized in their comments that none of the cost-saving, targeted collection efforts permitted under the Federal Rules can be realized without an operational capability to effectuate them. Ideally, the producing party can employ a defensible, targeted, and iterative search and collection process in-place, prior to collection to effectuate the proportional discovery process approved by the court in this decision. However, without such a capability, the alternative is an expensive, over-collection effort, where the data is searched post collection. Enabling the search iteration and targeted collection upstream brings dramatic cost savings, risk reduction, and other process efficiencies.

Usage-Based Pricing Model Increasingly Driving eDiscovery Software Growth

by John Patzakis

Legal Tech software CEOs often grapple with two competing challenges: Growing revenue in a manner that supports how customers buy their products for their individual cases, while at the same time maximizing shareholder value by recording recurring revenue, which the investor community typically favors. Recurring revenue generally comes in the form of fixed annual or monthly subscription licenses.

However, eDiscovery software providers are increasingly aligning their SaaS pricing strategy with the amount of product usage their customers consume. Instead of paying a fixed rate, the pricing is based upon actual usage. The benefits of this approach include a shorter and simpler purchasing process and increased customer satisfaction and retention.

In the eDiscovery space, customers often prefer to pay by “matter”, i.e., per lawsuit or legal case. Law firms and service providers typically utilize eDiscovery SaaS software specific to an individual case on a pass-through cost basis, where their end-client ultimately pays for the services. In the case of corporate law departments, oftentimes the organization prefers to purchase annual subscriptions for eDiscovery and apply the license over multiple matters in the course of the year. However, such buying decisions vary by organization, with corporate counsel sometimes deferring eDiscovery workflow and tech decisions to their law firms, which favors a usage-based pricing model.

While tech companies with recurring annual term revenue will typically garner higher valuations, eDiscovery software firms with usage-based pricing models are now seeing similarly elevated valuations. Investors are recognizing the very unique economics and buying dynamics specific to the eDiscovery software space. But it is incumbent on eDiscovery software execs, their investment bankers, and board members to educate the broader market on this dynamic unique to the eDiscovery space. In some situations, investors new to this space attempt to apply a steep discount to usage-based SaaS revenue, as it doesn’t fit in with their “paint by the numbers” ARR models. Rick Weber, Managing Director of Legal Tech investment banking firm Arbor Ridge Partners notes, “while the usage model is not annual recurring, it is ‘monthly re-occurring,’ and thus projections and modeling can be made based on company history and industry norms and should be treated like ARR contracts.”

In fact, usage-based pricing is now gaining wider acceptance in the broader SaaS software market beyond legal tech. Cloud infrastructure providers AWS and Microsoft Azure are obvious examples of successful usage-based pricing strategies, but many startups and medium sized companies have successfully implemented the model as well. While usage-based revenue may seem less predictable compared to other pricing models, companies using this model are often growing faster, retaining more revenue, and valued at high revenue multiples. But again, this realization requires a closer look by investors and an intelligent education effort by the companies and their advisors.

One caveat for investors is to confirm that the value of the SaaS usage offering is mostly based upon proprietary software tech versus services that are dressed up as SaaS. Some eDiscovery service providers attempt to position their services as SaaS, without a true standalone propriety software component. An analysis of the cost of sales/gross margins and assessment of the actual proprietary nature of the software is determinative. Gross margins should be at least 80 percent. And while some services are often provided in conjunction with a SaaS usage-based offering, a qualifying factor is whether the software is also separately offered purely as a traditional license to end users without any services required, which is how many customers will opt to buy.

But for true usage-based SaaS offerings, the flexibility, simplicity and supporting of legal customers purchasing dynamics are key to rapid growth and customer satisfaction. As summarized by Weber, “many of the PE firms and investors that have made big bets on such companies in recent years seem to understand the nuance and opportunity while many still lag behind and simply need to think outside of their box.”

ILTA eDiscovery Survey Highlights Targeted ESI Collection as the Preferred Methodology

By John Patzakis


The International Legal Technology Association (ILTA) recently published a very informative and comprehensive law firm eDiscovery practice survey, “2021 Litigation and Practice Support Survey.” ILTA received responses from litigation support professionals from 82 different law firms ranging in size from medium to large, on a variety of subjects, including eDiscovery practice trends and software tool usage. While the survey addresses a variety of aspects of legal tech and litigation, the survey reveals a couple of very notable insights regarding ESI collection in the enterprise.

The first important insight reflects that targeted ESI collection is the clear preferred method over forensic collection for litigation support purposes. Fifty-nine percent of respondents preferred “targeted collection (non-forensic)” as their standard methodology, while 13 percent still preferred forensic imaging. Forensic collection is rightfully on the decline as a method of ESI collection, as legal counsel seeks to leverage proportionality concepts that greatly reduce cost, time and risk associated with otherwise inefficient eDiscovery.

However, attaining the benefits of targeted collection requires the ability to operationalize workflows as far upstream in the eDiscovery process as possible. For instance, when you’re engaging in data over-collection, which in turn runs up of a lot of human time and processing costs, the ship has largely sailed before you are able to perform early case assessments and data relevancy analysis, as much of the discovery costs have already been incurred at that point. The case law and the Federal Rules provide that the duty to preserve only applies to potentially relevant information, but unless you have the right operational processes in place, you’re losing out on the ability to attain the benefits of proportionality. That is why we see forensic imaging, the epitome of data over-collection, on a steep decline.

The second notable takeaway was that network file shares and “loose files” were the most common form of collection data sources, even outpacing email. Network file shares are a significant challenge with data volumes, typically 10 to 20 terabytes, but can be much higher. Nearly every company and government agency maintains such large file shares, sometimes hundreds of them, depending on the size of the organization. Large network file shares can be found on premise or in a company’s cloud environment.

Traditional eDiscovery collection methods fail to efficiently address these large file shares, due to significant logistical challenges. The data cannot simply be searched in-place by traditional forensics tools or other crawling methods. Consequently, the data is typically copied in bulk and then migrated to another location for processing, where the data is finally indexed and then searched and culled. This approach does not enable the targeted, proportional collection methods preferred by law firms, as noted above.

To accomplish the goals of both targeted collection and addressing large file shares, index and search in-place technology should be utilized. Indexing and search in-place in this context means that a software-based indexing technology (as opposed to an expensive and cumbersome stand-alone hardware appliance) is deployed directly onto the file server or an adjacent computing resource. This indexing occurs without a bulk data transfer of the data. Once indexed, the searches are performed in a few seconds, with complex Boolean operators, metadata filters and regular expression searches. The searches can be iterated and repeated without limitation, which is critical for large data sets.

These capabilities supporting targeted and proportional collection of loose files, emails, and large network file shares are uniquely provided in the X1 Enterprise Platform.

Post Pandemic, Corporate eDiscovery Undergoes a Permanent Paradigm Shift

By John Patzakis

While the pandemic disrupted the workplace during its height, it is now becoming clear that a more permanent transformation has taken place. Employees and their electronic information assets are far more geographically dispersed. This is requiring corporate legal departments to rethink how they conduct eDiscovery, as the old model based upon data over-collection is no longer tenable. Instead, corporations are favoring a more targeted approach to ESI collection.

Industry analyst Greg Buckles of the eDiscovery Journal recently provided a good analysis on this topic:

“The sheer volume of raw custodial collections has put pressure on discovery professionals to use an iterative selective collection strategy. That puts the corporate legal team closer to scoping and collection activities than most have been. For too long corporate legal has felt uncomfortable pushing back on overly burdensome or broad discovery requests from opposing or retained counsel. The recent development of proportionality frameworks, guidelines and tools has the potential to empower corporate legal to make defensible cost-risk arguments.”

Buckles further observes that “some of my clients have drastically cut their eDiscovery related expenses through these kinds of initiatives.” He terms this as a “grand enterprise reboot” that “brings (corporate legal) to the table with a fresh perspective.”

Most core eDiscovery costs (outside of attorney review) stem from over-collection of ESI. While direct collection costs can seem inexpensive, law firm Nelson Mullins notes that “over preservation tends to have its own costs relating to storage of large amounts of electronically stored information (ESI) and the resources needed to manage it; leads to increased downstream e-discovery costs associated with collection, processing, and review.”

As outlined by Buckles, proportionality-based eDiscovery is an important principle that all corporate attorneys should be leveraging. Under Federal Rule of Civil Procedure 26(b)(1), parties may discover any non-privileged material that is relevant to any party’s claim or defense and proportional to the needs of the case. However, attorneys representing enterprises are essentially flying blind on this analysis when it matters most. Prior to the custodian data being actually collected, processed and analyzed, attorneys do not have any real visibility into the potentially relevant ESI across an organization. This is especially true in regard to unstructured, distributed data, which is invariably the majority of ESI that is ultimately collected in a given matter.

If accurate pre-collection data insight were available to counsel, that game-changing factor would enable counsel to set reasonable discovery limits and ultimately process, host, review and produce much less ESI. Counsel can further use pre-collection proportionality analysis to gather key information, develop a litigation budget, and better manage litigation deadlines. Such insights can also foster cooperation by informing the parties early in the process about where relevant ESI is located, and what keywords and other search parameters can identify and pinpoint relevant ESI.

A solution to these challenges is the utilization of index and search in-place technology. Indexing and search in-place in this context means that a software-based indexing technology is deployed directly onto file servers, laptops or even in the cloud to address cloud-based data sources. This indexing occurs without a bulk data transfer of the data. Once indexed, the searches are performed in a few seconds, with complex Boolean operators, metadata filters and regular expression searches. The searches can be iterated and repeated without limitation, which is critical for large data sets.

But it is important that the technology employed truly enables index-in-place, with the indexes deployed directly onto the laptops, file shares or cloud servers where the data exists. Some providers will market their tools as such, but the indexing and searching actually takes place in their platform at a central location. Data must first be copied and collected off of laptops and file servers and migrated over the network to get the indexing engines. This does not scale for eDiscovery.
